Parameters

mhi

Type: OpenCvSharp.CPlusPlusInputArray
Motion history single-channel floating-point image.

mask

Type: OpenCvSharp.CPlusPlusOutputArray
Output mask image that has the type CV_8UC1 and the same size as mhi. Its non-zero elements mark pixels where the motion gradient data is correct.

orientation

Type: OpenCvSharp.CPlusPlusOutputArray
Output motion gradient orientation image that has the same type and the same size as mhi. Each pixel of the image is a motion orientation, from 0 to 360 degrees.

delta1

Type: SystemDouble
Minimal (or maximal) allowed difference between mhi values within a pixel neighborhood.

delta2

Type: SystemDouble
Maximal (or minimal) allowed difference between mhi values within a pixel neighborhood. That is, the function finds the minimum ( m(x,y) ) and maximum ( M(x,y) ) mhi values over 3x3 neighborhood of each pixel and marks the motion orientation at (x, y) as valid only if: min(delta1, delta2) <= M(x,y)-m(x,y) <= max(delta1, delta2).

apertureSize (Optional)

Type: SystemInt32
