Hi, I am a senior year student of Computer Science. I am doing my undergrad thesis by the topic face recognition. I already done my face detection by using skin and hair segmentation and cropped the face. But I have a problem about eye detection, which is in my case I am not allowed to use any available library such as EmguCV, OpenCV, etc. I am trying to detect the eye by using the segmentation result, but here is where I am stuck. Can anyone give me idea about how to detect eyes? I am still working on it, but may be you can give me such useful advice? Thanks.
