Function opticalFlow

Stabilizes image objects between two consecutive frames caused by camera or object movement. Results are written to the points array.

prevGrayscale - Uint8Array of size (width * height). Grayscale data of previous frame

grayscale - Uint8Array of size (width * height). Grayscale data of current frame

textureShape - Should be {width, height, 1}

prevPoints - Float32Array of size (point count * 2). Positions of 2D points on the previous frame

points - Float32Array of size (point count * 2). Results are written here - positions of 2D points on the current frame

pointsShape - Should be {2, point count, 1}

winSize - Size of the search window for each pyramid level

maxLevel - Maximal pyramid level number, with zero based index

maxCount - Terminate if iteration count exceeds maxCount

epsilon - Terminate if window movement is less than epsilon
