Application of fuzzy set theory in detecting x-ray edges

An algorithm for extracting different regional boundaries of x-ray images is described which includes three-stage enhancement of the image in the fuzzy property plane and a smoother before the detection of edges. The property plane is extracted from the spatial domain using S and π functions and fuzzifiers. The operator 'contrast intensifier' is used as an enhancement tool. The final edge detection is achieved using '
\max
' or '
\min
' operator.
