how I can get eigenvalue from input image using Open CV? I need that eigenvalue to process poses from my image. when I get eigenvalue from image, I will put it in to my database. after that I could compute eigenvalue from real time camera so I can compare that eigenvalue and can know about what poses the user is shown. please help me. I don't know how difficulty this process.

if you really want the eigenvalues of the image, just convert to float, and use eigen() .
but, reading between the lines of your question, it sounds more like you want something like eigenfaces, pose recognition from images, or such ?
in that case, better read up on PCA, and look here.
