Coding of depth-maps using piecewise linear functions
Year: 2005
Type: article
Abstract: ... this paper, we propose a new algorithm for the coding of depth-maps that provides an efficient representation of smooth regions as well as geometric features such as object contours. Our algorithm uses a segmentation procedure based on a quadtree decomposition and models the depth-map content with piecewise linear functions. We achieved a bit-rate as low as 0.33 bit/pixel, without any entropy coding. The attractivity of the coding algorithm is that, by exploiting specific properties of depth-maps, no degradations are shown along discontinuities, which is important for depth perception
