## Detailed Description

Graph Based Segmentation Algorithm. The class implements the algorithm described in [53] .

## Member Function Documentation

## § 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

Python:
| retval | = | cv.ximgproc_segmentation_GraphSegmentation.getSigma( |  | )

## § 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

  src | The input image. Any number of channel (1 (Eg: Gray), 3 (Eg: RGB), 4 (Eg: RGB-D)) can be provided
  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.

## § setK()

virtual void cv::ximgproc::segmentation::GraphSegmentation::setK | ( | float | k | ) |
| pure virtual

Python:
| None | = | cv.ximgproc_segmentation_GraphSegmentation.setK( | k | )

## § setMinSize()

virtual void cv::ximgproc::segmentation::GraphSegmentation::setMinSize | ( | int | min_size | ) |
| pure virtual

Python:
| None | = | cv.ximgproc_segmentation_GraphSegmentation.setMinSize( | min_size | )

## § setSigma()

virtual void cv::ximgproc::segmentation::GraphSegmentation::setSigma | ( | double | sigma | ) |
| pure virtual

Python:
| None | = | cv.ximgproc_segmentation_GraphSegmentation.setSigma( | sigma | )
