Representative images at each stage. (a, b) The depth images represented by HSV format. (c, d) The grey image corresponding to the depth images in (a, b), respectively. (e) The result of difference algorithm. (f) The 3D perspective view of the result in (e). The representative results (represented in 3D perspective view) using the different denoising algorithms: (g) average filtering, (h) median filtering, (i) Gaussian filtering, (j) bilateral filtering, and (k) two-stage PCA filtering. (l, m) The PSO denoising results in 3D and 2D, respectively. (n, o) The results obtained by the segmentation algorithm based on MSER.
