Lecture 24: Histogram Processing - Part 3 (Histogram Specification or Histogram Matching)

This lecture discusses an important operation, called Histogram Specification (or Histogram Matching), related to histogram processing in digital images. Histogram specification method develops a gray level transformation for the histogram of an input image such that the histogram of the output image matches that of the pre-specified histogram of a target image. Histogram specification is useful when we have an image (target image) of good contrast and we want to match the histogram of other images (input images) to the histogram of this given image (target image).
