PyGaze: Open-source toolbox for eye tracking in Python This is the homepage to PyGaze, an open-source toolbox for eye tracking in Python. What to do next? We import the libraries Opencv and numpy, we load the video eye_recording.flv and then we put it in a loop so tha we can loop through the frames of the video and process image by image. Nothing fancy, super simple to implementate. For that, we are going to look for the most circular object in the eye region. There are many more tricks available for better tracking, like keeping your previous iterations blob value and so on. Usually some small objects in the background tend to be considered faces by the algorithm, so to filter them out well return only the biggest detected face frame: Also notice how we once again detect everything on a gray picture, but work with the colored one. Lets define a main() function thatll start video recording and process every frame using our functions. If not for them, the program would crash if you were to blinked. _ stands for an unneeded variable, retval in our case, we dont need it. Find centralized, trusted content and collaborate around the technologies you use most. You can see that the EAR value drops whenever the eye closes. Well cut the image in two by introducing the width variable: But what if no eyes are detected? Thanks. In order to know if a pixel is inside a pixel or not, we just test if the euclidean distance between the pixel location and the circle center is not higher than the circle radius. Learn more. Clone with Git or checkout with SVN using the repositorys web address. I dont think anyone has ever seen a person with their eyes at the bottom of their face. identify face --- identify eyes ---blob detection ---- k-means clustering for left and right ---- LocalOutlierFactor to remove outlier points -----mean both eyes ----- percentage calculation ------.

You can do it through the VideoCapture class in the OpenCV highgui module. Lets take a deep look in what the HoughCircles function expects: Well, thats it As the function itself says, it can detect many circles, but we just want one. My github is http://github.com/stepacool/ you can find eye tracking code here that uses some advanced methods for better accuracy. # PyMouse or MacOS bugfix - can not go to extreme corners because of hot corners? the range of motion mouse is 20 x 20 pixels. Now, the way binary thresholding works is that each pixel on a grayscale image has a value ranging from 0 to 255 that stands for its color. On it, the threshold of 42 is needed. opencv-eye-tracking Uses haarcascade_eye.xml cascade to detect the eyes, performs Histogram Equalization, blurring and Hough circles to retrieve circle (pupil)'s x,y co-ordinates and radius.

Its said that that new classifier is a linear combination of other classifiers. Each pixel can assume 255 values (if the image is using 8-bits grayscale representation). So we just make it _ and forget about it. But theres another, the Computer Vision way. You pass a threshold value to the function and it makes every pixel below the value 0 and every pixel above the value the value that you pass next, we pass 255 so its white. If nothing happens, download GitHub Desktop and try again. # process non gaze position events from plugins here. #filter by messages by stating string 'STRING'.
