I am the moment trying to convert a rgb to hsv, which seems impossible.. I thought i might have been due the Mat being empty.. but thats not the case... I get this error message. /build/buildd/opencv-2.4.8+dfsg1/modules/imgproc/src/color.cpp:3642: error: (-215) depth == CV_8U || depth == CV_16U || depth == CV_32F in function cvtColor for these lines of code.. Point find(Mat frame) { Mat imgOriginal = frame.clone(); Mat imgHSV = frame.clone(); if (frame.empty()) { cout << "Empty...'; exit -1; } cvtColor(imgOriginal, imgHSV, COLOR_BGR2HSV); //Convert the captured frame from BGR to HSV what could be going wrong here???
