Parameters

mhi

Type: OpenCvSharpCvArr
Motion history image

mask

Type: OpenCvSharpCvArr
Mask image; marks pixels where motion gradient data is correct. Output parameter.

orientation

Type: OpenCvSharpCvArr
Motion gradient orientation image; contains angles from 0 to ~360°.

delta1

Type: SystemDouble
The function finds minimum (m(x,y)) and maximum (M(x,y)) mhi values over each pixel (x,y) neihborhood and assumes the gradient is valid only if min(delta1,delta2) <= M(x,y)-m(x,y) <= max(delta1,delta2).

delta2

Type: SystemDouble
The function finds minimum (m(x,y)) and maximum (M(x,y)) mhi values over each pixel (x,y) neihborhood and assumes the gradient is valid only if min(delta1,delta2) <= M(x,y)-m(x,y) <= max(delta1,delta2).

apertureSize

Type: OpenCvSharpApertureSize
Aperture size of derivative operators used by the function: CV_SCHARR, 1, 3, 5 or 7 (see cvSobel).
