Type-2 Fuzzy Logic for Edge Detection of Gray Scale Images

Image processing is characterized by a procedure of information processing for which both the input and output are images, such as photographs or frames of video [Jain’86]. Most image processing techniques involve treating the image as a two-dimensional signal and applying standard signal processing techniques to it.[webpage1] Fuzzy Image Processing (FIP) is a collection of different fuzzy approaches to image processing. Nevertheless, the following definition can be regarded as an attempt to determine the boundaries. Fuzzy image processing includes all approaches that understand, represent and process the images, their segments and features as fuzzy sets. [webpage2]The representation and processing of the images depend on the selected fuzzy technique and on the problem to be solved [Jang’95]. Here is a list of general observations about fuzzy logic:  Fuzzy logic is conceptually easy to understand.
