Paper Abstract
Parametric edge detector has been reported to be successfully applied in actual coherent ladar intensity images corrupted
by speckle. But there are isolated erroneous test points in the image processed by parametric test detector. By
morphological filter, most isolated missing pixels in edge image background can be removed. Thus, the error of the edge
detection can decrease exceedingly which is useful for subsequent image processing. Edge detection plays an important
role in ladar image processing. Its capability has direct influence on precision and performance of ladar imaging system.
Therefore it is necessary to evaluate the performance of a detector. In order to demonstrate the advantages of
morphological filter based on parametric edge detection, the probability that an image pixel may be marked as an edge
by this detector is calculated. This detector is applied to detect a large number of images degraded by speckle with
different patterns and different carrier-noise-ratio. From the simulation results, the performance of morphological filter
based on parametric edge detection is described.
