Claim 8:
9. An image denoising device, comprising a processor configured to:
perform edge detection on a color image to obtain a preprocessed image;
acquire a depth image having the same scene as the color image;
perform a first noise reduction process on the preprocessed image according to the depth image to obtain a first image;
extract boundary pixels from the first image;
modify initial parameter values of the boundary pixels in the first image to obtain a second image;
perform a second noise reduction process on the second image to obtain a third image;
modify parameter values of the boundary pixels in the third image to the initial parameter values to obtain a fourth image; and
perform 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.
