Abstract:In order to improve both the speed and efficiency of the identification, this paper put forward the chain-code disperse curvature algorithm with the generalization of the definition of curvature in calculus into the disperse domain based on the chain-code representation of the edge of images. Then obtained the disperse curvature of the contour of images through chain-code, which could be used along with certain functions used for image matching, to identify objects in some fields that featured underwater remote-sensing images with high resolution and low SNR such as SAS. The experimental result shows that this algorithm has better identification efficiency with relatively low complexity than traditional ones that are based on feature extraction.......
