OpenCV TypeError: Expected cv::UMat for argument 'src' - What is this?

Question

Disclaimer: huge openCV noob

Traceback (most recent call last):

File \"lanes2.py\", line 22, in

canny = canny(lane_image)         


        

Answer 1

gray = cv2.cvtColor(cv2.UMat(imgUMat), cv2.COLOR_RGB2GRAY)

UMat is a part of the Transparent API (TAPI) than help to write one code for the CPU and OpenCL implementations.
