hello, I just cannot get the Matlab module of the opencv_contrib working at all;

I downloaded latest opencv and opencv_contrib, compiled properly with Visual Studio 2013 (everything is fine with Cmake: python is found, Matlab is enabled, and I get "Matlab: Compiler/generator: Working")

no errors in the compilation of the solution; I build the INSTALL and get the folder "matlab" in the install folder; open matlab, add the path with addpath; "help cv" works fine "cv.buildInformation" works fine

but any other function call fails;

e.g. img = cv.IMREAD_COLOR('d:/temp/Desert.png'); fails with: Index exceeds matrix dimensions.

or: camera=cv.VideoCapture();

or: there is no cv.dft as suggested in the help page of the Matlab module github page

what's wrong? any idea?

bear with me, no idea about matlab, but cv.IMREAD_COLOR is supposed to be a constant, to be used like: cv.imread('d:/temp/Desert.png', cv.IMREAD_COLOR);

thanks berak, your words turned on the key solution: the compilation was failing because... there was a space char in the folder name; after I removed it, compilation works and in matlab I have all functions; so, for people that use it under windows, remember that compilation suffers of spaces in the folder names;

I have now a question on the fact that the funcion helps (e.g. help cv.dft) doesn't work; I will write a new post for this;
