ImageSegmentationFilter

ImageSegmentationFilter[image,marker]

segments part of image specified by marker and returns an image mask.

Details and Options

  • ImageSegmentationFilter segments objects or components of interest in an image and returns it as a single-channel image. It is also known as image matting and foreground separation.
  • The following marker specifications can be given:
  • possegments the component containing the position pos
    {pos1,pos2,…}segments the component containing all posi
    Rectangle[…]segments the component indicated by a bounding box
  • The following options can be given:
  • PerformanceGoal Automaticaspects of performance to try to optimize
    TargetDevice"CPU"the target device on which to perform training
  • Possible settings for PerformanceGoal include:
  • Automaticautomatic tradeoff between speed and quality
    "Balanced"medium quality for average speed
    "Quality"optimize for quality of final results
    "Speed"optimize for speed of getting results
