Hello, I am able to detect eye pair in a colour images. Recently I have got a night vision camera and I am unable to detect eye pairs using vision.cascadeobjectdetector function in that night vision image. May be because of change in black colour of the eye in night vision. Need your help in detecting eye pair in those images. I have also attached image and code.

And I am able to detect face, mouth etc but not the eyes.

hello how to detect eye pair in a colour image can you help me?

[Walter Roberson]

haider shamil: you would use vision.CascadeObjectDetector .

The particular Question here had to do with the eyes having colors not expected by Cascade Object Detector because of the infrared nature of the photographs.
