Detailed Description

Possible options of image segmentation.

The segmentation options can be roughly gathered in 3 different groups:

• Preprocesing options: they are applied before the segmentation algorithm is performed.

  They are intended to improve the segmentation performance.

• Algorithm parameters: they are used to perform the Felzenswalb-Huttenlocher algorithm.

  The variation of these options can lead to very different segmentations of the same image, each with its own properties.

• Postprocessing options: they are applied once the segmentation algorithm is performed.

  They are intended to refine the segmentation supplied by the algorithm

Member Data Documentation

size_t _SegmentationOptions::expectedParents

Expected total number of parents (= spots) after the segmentation. This magnitude is used as an estimation of the memory to be allocated. Nevertheless a reallocation is carried out, whenever this number is exceeded. So this parameter is meant only to increase the performance of the application. Warning: This parameter must take a positive ( ) integer.

FrameProcessing _SegmentationOptions::frameMedian

Type of frame processing applied < when performing median filter. Setting values: Are those provided by the enum type #FrameProcessing

bool _SegmentationOptions::shouldDisolveExtremeSpots

Turns on post-segmentation merging of extremely small spots. Setting values: false : no merging of extremely small spots is done at all. true : merging of extremely small spots with the adjacent spots is carried out.

bool _SegmentationOptions::shouldPerformMedianFilter

Turns on pre-segmentation median filtering. Setting values: false : no median filter is performed. true : median filter is performed. Therefore the possibility of smoothing the noise of the image, before performing the segmentation, is given through this parameter.
