please can you tell me what filtering you applied to the video stream from your webcam??

seems like you converted the frames to gray4 scale then dilated then thresholded

please give a few hints man. i'm developing gaze tracking based cursor moving project. So far, my code in python slowly just detects the eyes

@ak2agent26 I used fast face detection to only look at the region around the face. Then I converted to greyscale, and equalized the histogram. Then I used the standard HaarDetectObjects with haarcascades for eyes - with Canny pruning switched on.

I had some hard-coded heuristics for narrowing down the possible eye matches - like checking I had one left eye and one right eye.

@timwintle dude fast face detection did you mean you applied simple template matching based tracking? 'cause that's the best i can think of to be 'fast'

also, please drop a few hints about gaze estimation. did you use model based or appearance based technique? please help me a little man

i'd appreciate it.

This is the first Google result for "eye tracking python".

More info would be appreciated.

Where's the code?
