Rendering Lossless Compression of Depth Image

Summary form only given. In this work, we experimented on the compression efficiency of rendering lossless compression of depth images and found that the compression ratios can go up to 20.51 and 40 for Interview and Breakdancer test images, respectively, even if the parameter setting is in the worst case (i.e., set fdensity(Znear, Zfar) to its maximum value). This work is our first step toward exploring the performance of rendering lossless compression. It is our belief that, besides the rendering lossless quantization, there are a lot of different issues of depth image compression which are worthy of further exploitation.
