This paper presents an image denoising method based on bilat eral filtering and non-local means.Non-local means method which was proposed in recent years is one of the great performing methods.And co mpared with the classical denoising methods,bilateral filtering method has a better performance in denoising for the reason that the weight include the geometric closeness and the intensity similarity.And accordingly this paper improve the we ight of the non-local means method.This paper combines the geometric closeness factor with the weight of Non-local means and constructs a new weight.Experiment shows that the modified algorithm can achieve better performance.And it can protect the image d etail and structure information better.
