title: AN ALGORITHM OF BOUNDARIES DETECTION IN LOW-CONTRAST RADAR IMAGES OF THE EARTH
abstract: 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
