Abstract

Parametric edge detector has been reported to be successfully applied in actual coherent ladar intensity images corrupted by speckle. Parametric edge detector derived from an exponential model for the speckle which has been described as a multiplicative noise corrupting intensity images. The performance of the noises is not the same when the intensity images are gained in different distance. So the application scope of this algorithm is of great value in actual ladar. In the paper, parametric edge detector, morphological filter based on parametric edge detector and Canny detector are used to detect coherent ladar simulated intensity images. The edge detection results are obtained and compared, when the values of carrier-noise-ratio (CNR) are changed. From the simulation results, the best application scope of parametric edge detection is described.
