A Method for Image Enhancement Based on Fuzzy Logic and Partial DifferentialEquation
Pang Yu-hong · Microcomputer Information · 2009
In this paper,a method for image enhancement based on fuzzy edge judgment and Partial differential equation(PDE) is proposed.The appropriate image processing operators are chosen through the fuzzy reasoning in the different areas.Contrast enhanced operator is an improved Beghdadi factor and image smoothing filter operator is used by PDE.The algorithm in this paper can obtain good results in edge enhancement,filtering out noise and protecting the details,and has strong flexibility and scalability through comparing the results with those of several image enhancement algorithms.
