2013-04-28 12:40:55 -0600	asked a question	Image step is wrong I am using the createEigenfaceRecognizer() to train and predict faces. When i use the databases like AT&T etc with the .pgm images, it works just fine. But when i use my own jpeg images i get the error ---Image step is wrong (Matrix must be continuous). When i use first ten images to be the AT&T .pgm s and next ten to be my imgaes (both are same pixels), i get the error ---Expected xxxx pixels, but is 0 pixels This thread seems to have the same kind of problem but it is on Visual Studio. But im working on Android OpenCV, therefore Eclipse IDE. Please help me out with this. Thank you :)
