  • Abstract
    This paper addresses the problem of estimating abrupt changes corrupted by multiplicative noise. Two estimators are considered depending on the noise assumptions: the Maximum A Posteriori (MAP) estimator and the Least-Squares (LS) estimator. Both estimators are computed using dynamic programming. This study is then applied to edge detection in SAR images.
