Description

Hi,

today, I solved my problem with the following exception being thrown:

OpenCV Error: Bad type of mask argument () in cvFindCornerSubPix, file /build/src/OpenCV-2.3.1/modules/imgproc/src/cornersubpix.cpp, line 71
terminate called after throwing an instance of 'cv::Exception'
what(): /build/src/OpenCV-2.3.1/modules/imgproc/src/cornersubpix.cpp:71: error: (-208) in function cvFindCornerSubPix

This error message does not even hint at the fact that the wrong type of image (rgb instead of grayscale) was being passed to the function.

Please improve this error message to hint at the possible error, for instance: "Bad type of mask argument(), possibly wrong image type. Please pass a monochrome image (Mat_<char>) as first argument."

Thanks!

Gašper
