Description

OpenCV 1.x optical flow allowed you to pass in pre-computed pyramids. Can we get this option back please.

I have a situation where I'm doing optical flow on the same image for different window sizes and would like to save time having to re-compute the pyramid. Every bit counts!

The feature is added to the OpenCV trunk.

There is a new function buildOpticalFlowPyramid for creating a pyramid which can be passed to calcOpticalFlowPyrLK instead of image.
