Parameters

img

Type: OpenCvSharp.CPlusPlusInputArray
Input 8-bit 3-channel image.

mask

Type: OpenCvSharp.CPlusPlusInputOutputArray
Input/output 8-bit single-channel mask. The mask is initialized by the function when mode is set to GC_INIT_WITH_RECT. Its elements may have Cv2.GC_BGD / Cv2.GC_FGD / Cv2.GC_PR_BGD / Cv2.GC_PR_FGD

rect

Type: OpenCvSharp.CPlusPlusRect
ROI containing a segmented object. The pixels outside of the ROI are marked as "obvious background". The parameter is only used when mode==GC_INIT_WITH_RECT.

bgdModel

Type: OpenCvSharp.CPlusPlusInputOutputArray
Temporary array for the background model. Do not modify it while you are processing the same image.

fgdModel

Type: OpenCvSharp.CPlusPlusInputOutputArray
Temporary arrays for the foreground model. Do not modify it while you are processing the same image.

iterCount

Type: SystemInt32
Number of iterations the algorithm should make before returning the result. Note that the result can be refined with further calls with mode==GC_INIT_WITH_MASK or mode==GC_EVAL .

mode

Type: OpenCvSharp.CPlusPlusGrabCutFlag
Operation mode that could be one of GrabCutFlag value.
