I want to draw a bezier curve ( which is piece-wise drawn through a set of points ) on an empty canvas using OpenCV and Python. I then want to get the resultant image in matrix form.

To do this I used a small code to calculate the the points of the bezier curve and then rendered it using cv2.polylines. This works but it is too slow. I was wondering

(1) if there was a way to draw a bezier curve faster, using openCV (2) if I could do the drawing operation using the GPU to make this faster.

Any help would be much appreciated!

unfortunately, you cannot access gpu functionality from python at all.
