Hi Terence, i found this proyect very useful for my FGP. I´m having a problem when running the script eingesave.py. I´m using Python 2.7 on Windows 8 64 bits. I have all the libraries installed and my own database format. Jpg. When I run this script in the command windows, an error appears: "OpenCV Error: Assertion failed (ssize.area ()> 0) in unknown function, file .. .. .. src opencv modules imgproc src imgwarp.cpp, line 1723 Unexpected error: Traceback (most recent call last): File "C: Users William Desktop THESIS Python facerec2 eigensave.py", line 118, in [X, y] = read_images (sys.argv [1], (256,256)) File "C: Users William Desktop THESIS Python facerec2 eigensave.py", line 87, in read_images cv2.resize im = (im, sz) cv2.error: .. .. .. src opencv modules imgproc src imgwarp.cpp: 1723: error: (-215) ssize.area ()> 0 " What can be the problem? Thank you very much.
