Abstract

There is much speckle noise in images of active laser imaging which could decrease image quality. Here, a multidirectional line-type structure weighted morpholoical (MLWM) filter is designed to suppress this speckle noise. The experimental results show that the new MLWM filter has the best performance in terms of noise suppression and the capability of preserving detailed information of images in order for the subsequent processing of imaging system.
