Problem in train(method) using javacv in android

[kav...@amazinggadgetdeals.com]

The Train method in Face Recognition class always gives pixel error.

OpenCV Error: Unsupported format or combination of formats (In the Fisherfaces method all input samples (training images) must be of equal size! Expected 1920000 pixels, but was 310249 pixels.) in virtual void cv::Fisherfaces::train(cv::InputArrayOfArrays, cv::InputArray), file /home/saudet/projects/bytedeco/javacpp-presets/opencv/cppbuild/android-arm/opencv-2.4.10/modules/contrib/src/facerec.cpp, line 564

My recommendation would be to follow the instructions in the tutorial here:
http://docs.opencv.org/modules/contrib/doc/facerec/facerec_tutorial.html
If you get these kinds of errors even after following these
instructions, then please let me know! Thanks
