black white segmentation

--------------------------------
These menus are for performing segmentation of black & white images. There are three ways to do this:

  1. By picking bars from an image histogram. This is the most useful way to do it.
  2. By selecting individual pixels from the image. This is more time-consuming, usually.
  3. By selecting individual bitplanes from the image data. This is sometimes useful for crude segmentations.
  4. By performing one of two texture analysis techniques. These require that you have already created a punch-out bitmap, using one of the above methods, or perhaps one of the color segmentation methods. The purpose of the punch-out bitmap is to restrict the texture analysis to a subset of the image's pixels.
