DEPTH IMAGE DENOISING METHOD AND DENOISING DEVICE

摘要

The present disclosure discloses a depth image denoising method. In one embodiment, the depth image denoising method includes the following steps: decomposing an original depth image of a shot object into n layers of depth image, where n is an integer that is greater than or equal to two; denoising on each of the n layers of depth image, to eliminate isolated noise(s) in each of the n layers of depth image; and, merging the denoised n layers of depth image, to obtain a final denoised depth image. Correspondingly, the present disclosure also discloses a depth image denoising apparatus. With the depth image denoising method and/or denoising apparatus according to the present disclosure, not only isolated noise(s) in the original depth image can be eliminated, but also noise(s) which is/are connected to effective connectivity region of greater area can be eliminated effectively, thereby improving denoising effect.
