Hi everyone,

I'm new user and I'm trying to execute my program that uses opencv. It compiles but during the exeution it appears this error.

OpenCV Error: Assertion failed (s >= 0) in setSize, file /<path_to_opencv>/OpenCV/OpenCV-2.4.3/modules/core/src/matrix.cpp, line 115 terminate called after throwing an instance of 'cv::Exception' what(): /<path_to_opencv>/OpenCV/OpenCV-2.4.3/modules/core/src/matrix.cpp:115: error: (-215) s >= 0 in function setSize

Can you help me? I've search through the internet for solutions but I didn't find anything related.

Thanks!!

Ferran.-

Hi,

when you create your cv::mat one of the size values (row or column) is lower than 0. You can't create a matrix with a negative number of rows or columns.

In future questions you should provide the code which produce the error.
