Help with createFisherFaceRecognizer();

edit

Hi guys!

i'm newb on OpenCV, and i'm trying to execute the facerec_video.cpp from the sample sources...

my only change in the code is that i include the extensions needed in the source.

but i am having a problem when i try this part

// Get the height from the first image. We'll need this
// later in code to reshape the images to their original
// size AND we need to reshape incoming faces to this size:
int im_width = images[0].cols;
int im_height = images[0].rows;
// Create a FaceRecognizer and train it on the given images:
Ptr<FaceRecognizer> model = createFisherFaceRecognizer();
model->train(images, labels);
// That's it for learning the Face Recognition model. You now
// need to create the classifier for the task of Face Detection.
// We are going to use the haar cascade you have specified in the
// command line arguments:
//

more exactly on modes->rain(images,labels);

All my images test are in 325,325 pixels( 105625 pixels), i am using 4 pictures to each person, and am using 3 persons ... someone can help-me to fix please?

thx
