The Research about Level Set Function Application in Image Segmentation
Zhen Liu · Computer and Information Technology · 2009
Image segmentation is one of the key technologies in areas from image processing to image analysis.In order to solve the image segmentation problem that widely existed in the area of image processing and computer vision,geometric active contour model bring forward in this background.When studied geometric active contour model,we always look Level set function as a high- dimension function model for a evolution curve or a interface function ψ.In this paper,we based on the advantage and disadvantage aspects of the traditional level set function and the distance preserving level set function,imported a image parameter function v(I) instead of a constant parmeter,and offered a new funtion that is an adaptive distancepreserving level set function.We can solve the partial differential equation of this level set function,after endure with som fact data,then get the result of this function,at last,get basal figure and character.
