Similar Pixel Selection Based on Bilateral Filter for Image Denoising
LU Xiao-min · Journal of Guangdong Ocean University · 2010
To overcome drawback of bilateral filter that blurs the image feature to some extent,a bilateral image denoising method based on similar pixel selecting is proposed.For the pixel being processed,the pixels having pixel value are close to this pixel(called similar pixel) within its neighborhood in this image firstly.Then,according to the ratio of the selected similar pixels to all the neighborhood pixels,determine whether conduct bilateral filtering to the similar pixels or to all the pixels within the neighborhood.Simulation results prove that,compared with traditional bilateral filtering,the presented algorithm can remove noise and maintain image feature more effectively at the same time.
