Image monitoring has already been applied to each domain extensively,the digitization of image sampling will make the image monitoring have more abundant function and more flexible implementation method.

This paper introduces a concept of subjection degree based on the original Ostu algorithm and puts forward fuzzyOstu method;meanwhile,it ascertains the segmentation threshold by making use of sub-sampling image to improve algorithm efficiency.
