SAR图像斑点噪声的滤波方法研究

摘要

Aiming at SAR image speckle noises, the paper analyzes the speckle noise model, then puts forward a filter method process which combines an improved weighted median filtering with enhanced Lee filter, and fulfills the process in VC + +. Experiment validates that the method process, can effectively remove speckle noises from a SAR image while preserving its edge information%针对SAR图像的斑点噪声,分析斑点噪声的模型,给出一种改进的加权中值滤波和增强Lee滤波相结合的去噪方法流程,并用VC++实现这一方法流程.通过实例验证表明该方法流程能有效去除SAR图像中的斑点噪声和保持图像边缘信息.
