Open CV showing error
I am using openCV with python, this code is from http://docs.opencv.org/trunk/doc/py_tutorials/py_imgproc/py_colorspaces/py_colorspaces.html#converting-colorspaces
When I run it It gives an error
hsv=cv2.cvtColor(frame,cv2.COLOR_BGR2HSV) error: ......\src\opencv\modules\imgproc\src\color.cpp:3541: error: (-215) (scn == 3 || scn == 4) && (depth == CV_8U || depth == CV_32F)
Thank You.
