Each pixel is a photosensitive site that outputs a signal based upon the amount of light striking it. Although the actual “signal” produced by the photosite is ...

In addition, simultaneously, by considering the non-linearity of the median filter, the sequence in which these two techniques are applied over the input image will also be important. The results of applying this com ...
