The first and simpler ones were the grayscale transformations, where the output intensity value of a pixel depends only upon the intensity of the corresponding pixel in the input image. The second, slightly more complex form of processing that we saw is the image filtering operations, where the output intensity depends on a neighborhood rather than a single intensity value.

During our discourse on image filtering in Chapter 2, Image Filtering, we laid emphasis on how the aforementioned two approaches differ. However, there is some sense in which grayscale transformations and image filtering ...
