I want to find the center of eye pupil. Here are the steps that I followed:
1- Obtained eye image from the extracted face image:
2- Thresholding the grayscale eye image with the following settings:
Max value: 255
Threshold: 60
Threshold Type: CV_THRESH_BINARY
3- I can't find the contour of the eye pupil from the image above. So I applied dilatation first
opencv_imgproc.cvDilate(left_eye, left_eye, null, 3);
4- Need to rescale it:
opencv_imgproc.cvErode(left_eye, left_eye, null, 6);
Now the problem is to find eye center as fast as possible. How can I achieve such a goal?
