A method of image segmentation based on fringe pick-up

Generally speaking, image analysis is picking -up useful data and information from image. I mage segmentation is a important method in image analysis, in our paper, on the basis of summarizing predecesso's theory and experiment, think about practical application at the same time, we adopt a method of image segmentation based on fringe pick-up namely "line sca space band-pass filter". This method could decrease information amount consumedly, and provide enough preparative for automatic recognition of system after image segmentation.
