Claim 0:
1. An image denoising method, comprising:
performing edge detection on a color image to obtain a preprocessed image;
acquiring a depth image having the same scene as the color image;
performing a first noise reduction process on the preprocessed image according to the depth image to obtain a first image;
extracting boundary pixels from the first image;
modifying initial parameter values of the boundary pixels in the first image to obtain a second image;
performing a second noise reduction process on the second image to obtain a third image;
modifying parameter values of the boundary pixels in the third image to the initial parameter values to obtain a fourth image; and
performing a third noise reduction process on the boundary pixels in the fourth image to obtain a fifth image; wherein a degree of noise reduction of the third noise reduction process is lower than that of the second noise reduction process.
