◆ getK()

virtual float cv::ximgproc::segmentation::GraphSegmentation::getK ( )
pure virtual
Python:
retval=cv.ximgproc_segmentation_GraphSegmentation.getK()

◆ getMinSize()

virtual int cv::ximgproc::segmentation::GraphSegmentation::getMinSize ( )
pure virtual
Python:
retval=cv.ximgproc_segmentation_GraphSegmentation.getMinSize()

◆ getSigma()

virtual double cv::ximgproc::segmentation::GraphSegmentation::getSigma ( )
pure virtual

◆ processImage()

virtual void cv::ximgproc::segmentation::GraphSegmentation::processImage ( InputArray  src,
OutputArray  dst 
)
pure virtual
Python:
dst=cv.ximgproc_segmentation_GraphSegmentation.processImage(src[, dst])

Segment an image and store output in dst.

Parameters
srcThe input image. Any number of channel (1 (Eg: Gray), 3 (Eg: RGB), 4 (Eg: RGB-D)) can be provided
dstThe 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.
