A Level Set Method Based on the Adaptive Filter
Meibo Lv · Infrared Technology · 2007
A new level set method based on adaptive filter was proposed to solve the problem of the traditional level set that can not deal with the image with additive noise.First,a new speed stop item based on adaptive filter was presented to make the evolving front insensitive to the multiplicative noise,then evaluated the variance of homogeneous area was proposed to distinguish edge area from homogeneity area and preserved the edge.Last using the decreasing function of the local contrast image as the stop item evolved the level set function to get the final segmentation result.The experimental results showed that the developed algorithm could segment the image well while suppressing the multiplicative noise.
