У меня такая проблема,

когда я запускаю vs2010 (отладка)(open cv 2.4.0 )facerec _demo.cpp выдает мне программу эту ошибку

OpenCV Error: Image step is wrong (The matrix is not continuous, thus its number of rows can not be changed) in unknown function, file......\src\opencv\modul es\core>\src\matrix.cpp, line 801

Эта ошибка выводит меня на эту строку в facerec.cpp
(Fisherfaces ::train (InputArray src, InputArray _lbls)

Mat data = asRowMatrix(src, CV_64FC1); <-- this gets a exeption, not handled.

и я использую в базе данных pgm img, и это мой оригинальный файл *facerec _demo.cpp *
