Depth image denoising method

Abstract

The invention discloses a depth image denoising method which can reduce edge blur of images, is applicable to non-zero-mean Gaussian denoising and greatly improves depth image quality. The depth image denoising method includes the steps that 1, joint bilateral filtering is carried out on the depth images, the action scope of a bilateral filter is constrained, and accordingly filtered images are obtained; 2, a dictionary is trained through a K-SVD method, the filtered images of the first step are denoised through sparse representation on the basis of the dictionary, and reconstructed images are obtained.
