Abstract

An ellipse fitting method based on boundary was proposed to estimate the relevant parameters of ship target in SAR image which can effectively solve the problem of the ship targets extraction and parameters estimation in SAR image. For the least-squares ellipse fitting method, all of the sample points on the boundary were involved in operation and causing deviation of the final results of ellipse fitting. For this kind of situation, a least-squares ellipse fitting method based on boundary was adopted. First extracting edge of the image and piecewise fitting ellipse. Then evaluating the ellipse and choosing suitable ellipse area for the target to be detected. The experiment shows that it is an effective method.
