One of the problems of radar images analysis of the Earth is the detection of boarders between areas with different normalized effective radar cross-sections.In this paper, we propose a computationally effective quasi-optimal algorithm capable for building approximation of such boarders with straight line segments for low-contrast radar images and arbitrary line for high-contrast radar images.To achieve computational efficiency we apply image segmentation and later approximation.Efficiency of the proposed algorithm was examined on a number of computer generated radar image fragments including lowcontrast radar images.Proposed algorithm can be effectively implemented using modern parallel computation systems.
