Parameters

prev: Type: OpenCvSharpCvArr
First image, 8-bit, single-channel.
curr: Type: OpenCvSharpCvArr
Second image, 8-bit, single-channel.
blockSize: Type: OpenCvSharpCvSize
Size of basic blocks that are compared.
shiftSize: Type: OpenCvSharpCvSize
Block coordinate increments.
maxRange: Type: OpenCvSharpCvSize
Size of the scanned neighborhood in pixels around block.
usePrevious: Type: SystemBoolean
Uses previous (input) velocity field.
velx: Type: OpenCvSharpCvArr
Horizontal component of the optical flow of floor((prev->width - block_size.width)/shiftSize.width) × floor((prev->height - block_size.height)/shiftSize.height) size, 32-bit floating-point, single-channel.
vely: Type: OpenCvSharpCvArr
Vertical component of the optical flow of the same size velx, 32-bit floating-point, single-channel.
