Eye Twitching. How Stress Affects You. No one knows what causes this, which your doctor might call blepharospasm. When it happens, your eyelid, usually the upper one.. Great article, this is really impressive. In my case, my eye aspect ratio never goes much above 0.3 no matter how wide I open my eyes. Also, I missed some blinks with the 3 frame setting, maybe your frame rate is higher than mine. This is what works better on my system:Hello sir, Thank you so much for sharing this information. But i have faced some issue. when i detect my face then it complete consider blink but when i see any photos through webcam then it also consider blink how it possible?Hey Salman — you would need to train your own custom shape predictor for just the eyes. The method outlined in this blog post requires the entire face to be detected which in turns allows the eyes to be localized.Hi! Great tutorials on the site! Just to give you a suggestion; Could you also use an IR lighting rig to light up the subject at night time? Because most webcams have the capability to detect IR. Thanks!

Hey Adrian. Thanks for your knowledge and enthusiasm– Im (newish to python) and trying to get the blinks to trigger short midi sequences using pygame. I got it to work per se, but the video is paused during playback and then resumes after. Ideally it wouldnt, improving the timing of the next trigger (so they could potentially overlap.) I tried a couple threading situations, but couldnt seem to get the right configuration. Am i on the right track at least? thanks Do you know if there is a way to normalize de distance of the points, making it not dependig of the distance to the camera?

Understanding the “eye aspect ratio” (EAR)

If so, the next step is to start start incorporating facial landmark detection into the centroid tracking code. Detect landmarks for each face and visualize them. Make sure they are working.Using this simple equation, we can avoid image processing techniques and simply rely on the ratio of eye landmark distances to determine if a person is blinking.In this case, we make another check on Line 119 to see if a sufficient number of consecutive frames contained an eye blink ratio below our pre-defined threshold.

Hi, Thanks for the code. When i run the code, i get following two lines in output and not opening any video.And dont you have a problem when killing the thread in python? If I run your code, when I press q, the terminal lags and I have to shut down and open the terminal againSanjay as Dlib give so many warnings and errors like Cmake and windows 10 SDK, For Dlib installation first install Visual studio 2015 or latest, then install visual studio build tools 2019 and update C++ packages. which maybe 1 to 4GB. after successfull, then import Cmake library and after that import Dlib.

It is interesting to note that the green outlines around my eye always seem to show both eyes are roughly the same amount open, even when one eye is completely wide open and the other eye is entirely shut. Looks like the facial landmark detector (HOG) is making some assumption that the face should be symmetric, so both eyes should be about the same. Thanks for a great article. When I am running your code, the blink count is incremented even though I move here and there and keep my eyes open. How can I make it more accurate? Also can this code be implemented in java?

What made you want to look up eyeblinks? Include any comments and questions you have about this word Taken together, results from lesion, inactivation, and neural recording studies seem to demonstrate that the cerebellar cortex is not essential for basic eyeblink CR learning or retention, but that significant contributions from cortex underlie normal learning. Long term depression (LTD) at the PF-PC synapse is hypothesized to have significant functional consequences for learning the behavioral CR in EBC (Ito, 1984). For example, as a result of training, INP cells discharge prior to CR execution and fire in a pattern of increased frequency of response that predicts the temporal form of the behavioral CR (McCormick & Thompson, 1984). This pattern of activity clearly indicates that the INP is capable a generating a conditioned response. Purkinje cells of the cerebellar cortex tonically inhibit deep nuclear cells. Therefore, an LTD-mediated decrease in PC activity at the appropriate time during a CS-US interval could release the INP from tonic inhibition and allow for execution of a CR. An increase in PC activity could have the opposite effect, prohibiting or limiting CR execution. It has been hypothesized that CRs are generated by the INP as a result of release from PC inhibition (i.e. Perrett et al., 1993).

While both of these procedures require the cerebellum, the trace procedure also requires the hippocampus and medial prefrontal cortex.[4][5]

In either case it looks like your path to the shape prediction model is incorrect. Double-check your paths and ensure you are using Windows path separators (‘\’) instead of Unix path separators (‘/’).

eyeblink, Bratislava, Slovakia. 342 likes. treats dry eye by increasing your blinkrate. When low blinkrate occurs, Eyeblink will remind you to blink I’m confused >.> Are we supposed to be training a SVM on the feature vectors in real time or something? <.<Thanks for your great post.Your post has been a great help for my project. Could you explain this paragraph?

The first evidence for the role of the cerebellum in EBC came from McCormick et al. (1981). They found that a unilateral cerebellar lesion which included both cortex and deep nuclei permanently abolished CRs. In subsequent studies, it was determined that lesions of the lateral interpositus and medial dentate nuclei were sufficient to prevent acquisition of CRs in naïve animals (Lincoln et al., 1982) and abolished CRs in well-trained animals (McCormick & Thompson, 1984).[7] Finally, the use of Kainic acid lesions, which destroy neuronal cell bodies and spare passing fibers, provided evidence for a highly localized region of cerebellar nuclear cells that are essential for learning and performing CRs (Lavond et al., 1985). The population of cells critical for EBC appears to be restricted to a ~ 1 mm3 area of dorsolateral anterior INP ipsilateral to the conditioned eye. Lesions to this area of INP result in an inability to acquire eyeblink CRs in naïve animals. Additionally, the permanence of the localized lesion effect is remarkable. In well-trained animals, CRs abolished as a result of lesion are not reacquired, even after extensive training that spans over 8 months (Steinmetz et al., 1992). These results demonstrate that a highly localized region of cerebellum must be intact for CR learning to occur in EBC. Many many thanks for this tutorial, It really helped me a lot. Can you make a tutorial on improving the blink detector, as you mentioned in the “Improving our Blink detector”.(13-dim feature vector, SVM).The order in which stimuli are presented is an important factor in all forms of classical conditioning. Forward conditioning describes a presentation format in which the CS precedes the US in time. That is, from the perspective of the research subject, experiencing the US is contingent upon having just experienced the CS. EBC is usually, but not always, conducted in this manner. Other stimulus contingencies include backward conditioning, in which US comes before CS, and simultaneous conditioning, in which CS and US are presented at the same time. In any case, the time between CS onset and US onset is the interstimulus interval (ISI). Animals are usually trained with a shorter ISI than humans, which can make interspecies comparisons difficult.[2] The method works well on the images that need to have the face. In my dataset, I just have the left eye and right eye (similar to Figure 3 above) captured by the camera that attached to two eyes of the person.

error coming like this….. AttributeError: module ‘imutils.face_utils’ has no attribute ‘FACIAL_LANDMARKS_IDXS’ # loop over the face detections for rect in rects: # determine the facial landmarks for the face region, then # convert the facial landmark (x, y)-coordinates to a NumPy # array shape = predictor(gray, rect) shape = face_utils.shape_to_np(shape) # extract the left and right eye coordinates, then use the # coordinates to compute the eye aspect ratio for both eyes leftEye = shape[lStart:lEnd] rightEye = shape[rStart:rEnd] leftEAR = eye_aspect_ratio(leftEye) rightEAR = eye_aspect_ratio(rightEye) # average the eye aspect ratio together for both eyes ear = (leftEAR + rightEAR) / 2.0 Line 89 determines the facial landmarks for the face region, while Line 90 converts these (x, y)-coordinates to a NumPy array.

Refer to this blog post. We compute the “EAR” or “Eye Aspect Ratio”. You can do something similar with the mouth landmarks (perhaps a “Mouth Aspect Ratio”) just as a quick test. If that doesn’t work you can normalize the distance of the mouth by scaling it by the width of the face then trying to threshold on it.What are the specs of the computer you are using to execute the code? This code can easily run a modern day laptops/desktops.

Unfortunately, no. The facial landmark detector assumes you are working with the entire face. If you had just eye images and wanted to localize the eye you would need an eye detector + a trained shape predictor for the eye region.yeah..but I couldn´t find an aspect ratio for the smile. Also if I can solve this I can track all the others point of the face and notice differents expressionsYou can learn more about dlib’s facial landmark detector (i.e., how it works, what dataset it was trained on, etc., in this blog post).Hi Adrian, I am doing a University project and I wanted to incorporate a fatigue detection camera within the product I am making. Unfortunately I do not know anything about OpenCV, Python, and dlib or coding for that matter. Is there anyway you could help me?You can certainly detect winks, just compute the EAR for each eye and then track how long each eye has been closed for. As far as “looking down” you may want to adjust your camera placement or use a more advanced method for eye blink detection, perhaps one that uses multiple EAR inputs as a feature vector.

Thank you for this great article. I’m working on images of eyes (just eyes, no face) to find out the drowsiness. Is it possible to use dlib for the case the eyes are cropped out of the face? Or you have better suggestions.Hi, dhanush. I experienced this same error…..if u solved it please let me know how. =) thank you.To build our blink detector, we’ll be computing a metric called the eye aspect ratio (EAR), introduced by Soukupová and Čech in their 2016 paper, Real-Time Eye Blink Detection Using Facial Landmarks. # grab the indexes of the facial landmarks for the left and # right eye, respectively (lStart, lEnd) = face_utils.FACIAL_LANDMARKS_IDXS["left_eye"] (rStart, rEnd) = face_utils.FACIAL_LANDMARKS_IDXS["right_eye"] Using these indexes we’ll be able to extract eye regions effortlessly.

The VideoStream classes leverages threading and reduces I/O latency. See this blog post for more information.Hello Adrian, Thanks for making us more learned. Can you provide the code that represents EAR in real-time as Figure 5. I really want it and I hope you will join my requist.Can you clarify what you mean by “Python shell”?

Hey Malo — there are a few ways to approach this problem. Is there any particular reason you are relying strictly on the distance? You could attempt use an aspect ratio calculation here for the smile here as well.

Awesome work ..I and my team started from a scratch and by looking all your blogs finally after 4 days and 3 full nights I am able to count my blinks!!!..so happy!!…I modified your code little bit as I have used my android camera connected to server so i have not use FileVideoStream instead i used urllib and also i made some other changes like the dataset one and it took me 2 days just to install all the libraries ..Two cerebellar sites of CS-US convergence are 1) cells of the deep nuclear region in the cerebellum, and 2) PCs of the cortex[6]. In addition to receiving converging CS and US input via the PN and IO, respectively, cells of the cerebellar nuclei receive GABA-ergic inhibitory input from PCs of the cerebellar cortex. Output from the interpositus nucleus includes projections to the red nucleus, and the red nucleus sends projections to the facial and abducens nuclei. These nuclei supply the motor output component of the reflexive eyeblink. Therefore, in addition to being a site of stimulus convergence, the deep nuclei are also the cerebellum's output structure. I found that if I didn’t blink but moved my head back and forth, Blinks’ value would also increase, meaning the program thought I blinked. # check to see if the eye aspect ratio is below the blink # threshold, and if so, increment the blink frame counter if ear < EYE_AR_THRESH: COUNTER += 1 # otherwise, the eye aspect ratio is not below the blink # threshold else: # if the eyes were closed for a sufficient number of # then increment the total number of blinks if COUNTER >= EYE_AR_CONSEC_FRAMES: TOTAL += 1 # reset the eye frame counter COUNTER = 0 Line 111 makes a check to see if the eye aspect ratio is below our blink threshold — if it is, we increment the number of consecutive frames that indicate a blink is taking place (Line 112).

Hey Adrian, just a quick note to say thanks – we have used this as a base to build upon for a blink based lie detection system for a project at university. (we have credited you, of course!) We found that blink detection is improved a lot if the EAR threshold is dynamically set to respond to the mean of recent EAR values. Also, getting some nice graphical output tracking EAR and counting blinks really helped with algorithm tuning. Anyway, thanks for a super readable code – I enjoyed playing around with it. 🙂 Take care x

Hi, Adrian, I’ll bet this would be useful as part of a lie detector system used with other clues. That’s assuming that the person is not a pathological liar who is as comfortable with lying as with breathing. Such use has probably been done, ya? BTW did you know that the lie detector was invented by Dr. Marston who created the Wonder Woman comic? There’s a movie about it.I haven’t tried this method, but I know other PyImageSearch readers have gotten it to work. I would suggest starting there.

Unlike traditional image processing methods for computing blinks which typically involve some combination of:Hey I’m trying to add functionality of detecting when a tongue is sticking out but I’m having problems making it work. I’m trying to take the color above the lower edge of the lower lip and the color below it which are supposed to be pink above and skin color below and then when a tongue is sticking out its pink both above and below. But the color difference is not distinguishable enough. Do you have any other ideas?

Kip writes: Hey everyone! I am an animator and I'd like to share my experience with animation in Blender. This is my first tutorial to learn how to animate Eye Blinks in Blender Hi Adrian thanks for the detailed turorial! I have the same error like Arzoo,but I work on win10,dlib18.17,opencv3.1,python3.4.5 now I do not know how to solve it. can you please help me solve the problem. Looking for the definition of EYEBLINK? Find out what is the full meaning of EYEBLINK on Abbreviations.com! The Web's largest and most authoritative acronyms and abbreviations resource $ python detect_blinks.py \ --shape-predictor shape_predictor_68_face_landmarks.dat \ --video blink_detection_demo.mp4 And as you’ll see, we can successfully count the number of blinks in the video using OpenCV and facial landmarks:

Are you trying to plot the EAR over time? If so, I would suggest using matplotlib, Bokeh, or whatever plotting library you feel comfortable with.Once we have the facial landmarks for both eyes, we compute the eye aspect ratio for each eye, which gives us a singular value, relating the distances between the vertical eye landmark points to the distances between the horizontal landmark points.I got to this lesson through your 17-day class. Getting this one to work on my face live from my web camera is going to be an interesting exercise. I’m acquiring “old guy” face, the relevant parts of which are narrowed eyes and thick dark eyebrows. As applied in the provided code, the dlib software jumps back and forth between returning values for my actual eyes, or for the space between my eyes and eyebrows. Even when it’s using my actual eyes, their narrowness tends to fool the simple EAR test: it either thinks I’m blinking a lot, or not at all.Why after i run the code with your provided video file ,it shows an error:Nonetype object has no attribute shape when your video is over.

Very quickly; in a very short period of time A bit off topic – now days I am playing with YOLO to get real time object detection. I am trying to implement this in Python but without any success. Do you plan to cover this up?Thank You so much Adrian. I could resolve it. Actually i was installing imutils with the command ‘pip install imutils’. Thought it would get me the latest version. Isn’t it like that? Anyway now i given command ‘pip install imutils==0.5.1’, and problem is resolved. Thanks again.Also, I was hoping you can show me how to modify the code so that it doesn’t show the video but just works in the background.Enter your email address below to get a .zip of the code and a FREE 17-page Resource Guide on Computer Vision, OpenCV, and Deep Learning.
