Method Details

__fromPtr__

public static DenseOpticalFlow __fromPtr__(long addr)

calc

public void calc(Mat I0,
 Mat I1,
 Mat flow)

Calculates an optical flow.

Parameters:

I0 - first 8-bit single-channel input image.

I1 - second input image of the same size and the same type as prev.

flow - computed flow image that has the same size as prev and type CV_32FC2.

collectGarbage

public void collectGarbage()

Releases all inner buffers.
