Sprite coding is a new objected-based coding technology proposed by MPEG-4 video standard. In this paper. we propose an unsupervised sprite coding System for sport videos, for example. tennis sequences. Our system can provide several important functions. First, the sprite of the background can he generated without any pre-processing masks in our system. Second, it can automatically segment the foreground and background in a video sequence. Third. it can provide themasks of the foreground

The experimental results show that our system has a very good performance and the coding gain of our system compared with MPEG-4 Advanced Simple Profile is 2.5dB at the low bit rate (270Kbps) and is 2dB at the ultra low bit rate (7OKbps). It can he used in the spon video coding at low bit rate and provides a object-based sport video sequence.
