摘要: This paper describes a new method for removing geometric distortion in images of submerged objects observed from outside shallow water. We focus on the problem analyzing video sequences when water surface is disturbed by waves. The waves will affect appearance individual frames such that no single frame completely free distortion. suggests that, principle, it possible to perform selection set low sub-regions each and combine them form undistorted image object. novel contribution this use multi-stage clustering algorithm combined with frequency domain measurements allow us select best sequence. evaluate created both our laboratory, as well natural environments. Results show effective caused motion.
