We first present the Hypothesis Selection Filter in a general setting. For a given image enhancement problem, suppose we have selected a set of image filters each of which is effective in improving the image quality for a certain type of content. Our objective is to combine the filter outputs to obtain an overall best quality result. In the following, we use upper-case letters to denote random variables and random vectors, and lower-case letters to denote their realizations.
