black white segmentation

These menus are for performing segmentation of black & white images. There are three ways to
do this:
- By picking bars from an image histogram. This is the most useful way to do it.
- By selecting individual pixels from the image. This is more time-consuming, usually.
- By selecting individual bitplanes from the image data. This is sometimes useful for
crude segmentations.
- 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.
