A New Approach for Detection by Movement of Lips Base on Image Processing and Fuzzy Decision

Finding movements of lip for distinction of numbers are one of the functions of image processing and for achieving to this purpose. First, the input image was received by camera and it’s being developed for it’s processing by applying some filters and by using of gray criterion and measure that is on the base of green spectrum and then segmentation of pieces is being carried out on the image bye a compound segmentation algorithm with a set of special filters and in the next stage performs for distinction of lip’s movements from each other on the film according to these ways that first, the related frame to primary state and then the related frame to second state is computed and according to these two frames on the basis of criterions of the lip’s width, average of top and down angle of lip, linguistic variables and fuzzy sets and fuzzy rules is determined for finding lip’s movement. At last, the obtained result is being analyzed by a defuzzified method.
