Title The Theory and Implementation of SLIC Superpixels Segmentation Method
Abstract
The research of superpixel algorithms is becoming more active recent years in the field of image processing.Superpixel has gradually become an important method of image pre-processing and pre-segmentation.The method of piding original image into superpixels and using superpixels instead of original pixels to perform further high-level image understanding,could improve the speed of image processing.In recent years, a novel algorithm, SLIC,is widely used for its excellent features.It is simple to use, needing only one parameter species the number of superpixels;the quality of image segmentation is very high; while its computational cost should be very small.
This article detailedly describes the theory of SLIC superpixels segmentation method, including algorithm and complexity analysis . This article also gives the implementation of SLIC algorithm, with results of test on images, to show the specific features of SLIC algorithm.In the end,this article introduces current status of the research of SLIC method`s extension and application.
