A Survey on Motion Capture Data Compression Algorithm.

With the rapid development of data-driven animation technologies, huge motion capture data has been accumulated. Motion capture data is a kind of spatio-temporal high dimensional data, which needs a lot of storage space. Efficient compression and transmission of motion capture data has become a hot topic in computer animation. In this paper, we induce the characteristics of motion capture data and the general processing pipeline of motion capture data compression algorithm. Then we review the research achievements in the field of motion capture data compression for the last twenty years. According to reduced dimensions, running platform, lossy or lossless, motion data format, environment contact processing and progressivity, we put these motion capture data compression algorithms into different categories. Finally, we look forward to the future research trend.
