Utilisation Median Filter as Pre-Processing for Depth Map Compression

Abstract

Video compression is commonly studied, and several standards have been established from multimedia companies. The 3D video signal contains of the conventional 2D video signal and depth video. In order to equip 3D video, depth video compression has been explored to unveil geometric information for synthesis virtual views. Conventional video compression is not allowed directly employed into genuine depth video because its characteristics which may influence in compression ratio and synthesis representation. Depth information is able to be implemented for several images processing implementations such as identification, segmentation and so on. Unfortunately, the problem happens in original depth video begins from acquisition process of depth video. This depth video is needed to be compressed for efficient network transmission, storage and power. In this working, will be shown utilizing median filter as pre-processing method dues to its unstable pixel values. Then, the output of pre-processing was submitted into H.264/AVC encoding tool. From experimental results, utilizing median filter as a preprocessing approached the quality of video compression up to 20 % compared to the output depth video without using median filter at all.
