Fuzzy logic is a technique of emboding human like thinking into a control system. These find applications in modeling human brain and in the creation of behavioural systems. Fuzzy Logic based systems  provides a more efficient and resourceful way to solve Control Systems. These systems are been used in business, hybrid modelling , Air conditioners, video game artificial intelligence , pattern recognition in remote sensing and expert systems. Mainly the use of Triangular and Gaussian membership functions for FIS based edge detection is to provide simplicity, reliability and robustness.
