how to perform stable eye corner detection?

Question

For those who find it too long, just read the bold lines.

My project of gaze estimation based screen cursor moving HCI is now dependent on one last thin

Answer 1

i changed this

if ( x((colorImage.width/4)*3) ) and (y>40 and y<70):

to this:

if ( x<(w/5) or x>((w/4)*3) ) and (y>int(h*0.45) and y

because earlier i was just manually looking at pixel values beyond which i my windows where corners could be found with the highest probability. But then afterwards i realised, lets make it general, so i made a horizontal window of 45 to 65 pc of the Y range, and 1/5th to 3/4ths for X range, because that's the usual area within which the corners are.

I'm sorry guys for replying late, i was busy with the later part of the project - gaze estimation. And i'm gonna post a question about it, i'm stuck in it.

by the way, here are few pictures of eye corners and pupil detected in my eye: (enlarged to 100x100)

Hope this will be useful for others beginning in this area.
