In this paper, we propose a new patch-based image denoising algorithm using graph signal processing.
The concept of this algorithm is to take advantage of the redundancy of the BM3D transform and the edge preservation property of graph-based image processing.
More specifically, we collect similar patches in the image, and construct a graph by connecting obtained patches.
Then we apply a graph wavelet filter bank on graph signals to attenuate additive white gaussian noise by shrinking derived coefficients.
We apply our proposed algorithm to depth map denoising.
The experimental results demonstrate significant performance gains for the edge preservation and the noise reduction. |
