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.
