BM() публичный статический Метод

Calculates optical flow for overlapped blocks block_size.width * block_size.height pixels each, thus the velocity fields are smaller than the original images. For every block in prev the functions tries to find a similar block in curr in some neighborhood of the original block or shifted by (velx(x0,y0),vely(x0,y0)) block as has been calculated by previous function call (if use_previous)

public static BM ( Byte>.Image prev, Byte>.Image curr, Size blockSize, Size shiftSize, Size maxRange, bool usePrevious, Single>.Image velx, Single>.Image vely ) : void
prev	Byte>.Image	First image
curr	Byte>.Image	Second image
blockSize	System.Drawing.Size	Size of basic blocks that are compared.
shiftSize	System.Drawing.Size	Block coordinate increments.
maxRange	System.Drawing.Size	Size of the scanned neighborhood in pixels around block.
usePrevious	bool	Uses previous (input) velocity field.
velx	Single>.Image	Horizontal component of the optical flow of floor((prev->width - block_size.width)/shiftSize.width) x floor((prev->height - block_size.height)/shiftSize.height) size.
vely	Single>.Image	Vertical component of the optical flow of the same size velx.
Результат	void
