imagingbook.common.regions.RegionContourSegmentation
All Implemented Interfaces:
ContourTracer
public class RegionContourSegmentation extends BinaryRegionSegmentation implements ContourTracer

Binary region segmentation based on a combined region labeling and contour tracing algorithm as described in [1]. Detected regions and contours are 4- or 8-connected. See Sec. 8.2.2 of [2] for additional details.

  • Constructor Details

    • RegionContourSegmentation

      public RegionContourSegmentation(ByteProcessor ip)
      Constructor. Creates a combined region and contour segmentation from the specified image, which is not modified. The input image is considered binary, with 0 values for background pixels and values ≠ 0 for foreground pixels. The 4-neighborhood is used by default (BinaryRegionSegmentation.DefaultNeighborhoodT).
      Parameters:
      ip - the binary input image to be segmented

    • RegionContourSegmentation

      public RegionContourSegmentation(ByteProcessor ip, NeighborhoodType2D nh)
      Constructor. Creates a combined region and contour segmentation from the specified image and neighborhood type (4- or 8-neighborhood). The input image is considered binary, with 0 values for background pixels and values ≠ 0 for foreground pixels.
      Parameters:
      ip - the binary input image to be segmented
      nh - the neighborhood type (4- or 8-neighborhood)
