Methods

Create(Double, Single, Int32)

Creates a graph based segmentor

Declaration

ProcessImage(InputArray, OutputArray)

Segment an image and store output in dst

Declaration

public virtual void ProcessImage(InputArray src, OutputArray dst)

Parameters

Type	Name	Description
InputArray	src	The input image. Any number of channel (1 (Eg: Gray), 3 (Eg: RGB), 4 (Eg: RGB-D)) can be provided
OutputArray	dst	The output segmentation. It's a CV_32SC1 Mat with the same number of cols and rows as input image, with an unique, sequential, id for each pixel.
