An Improved Filter Algorithm Based on Prior Points

Abstract:

In this paper, we proposed two improved methods for impulse noise of image. Firstly we propose an improved multiple extreme value examine for pixels for pixels. Secondly we propose a variable threshold ,a point-set composed with prior pixels was proposed to determine the threshold value. The approach makes noise well-detected and can reduce lost and false noise relatively. Experiments confirm the validity and effectiveness of the method , and has the less computation.
