Artificial intelligence is exhibited by artificial entity, a system is generally assumed to be a computer. AI systems are now in routine use in economics, medicine, engineering and the military, as like computer chess and other video games. It includes various advanced systems such a Neural Network, Fuzzy Systems and Evolutionary computation. Fuzzy logic is a powerful tool to represent and process human knowledge in form of fuzzy if-then rules. The manipulation of these concepts leads to theory of approximation using fuzzy systems in image processing. If the observed data are distributed by random noise then the fuzzification operator should convert the probabilistic data into fuzzy numbers or fuzzy data.
