The adaptation principle of this code is to dynamically change the mapping relationship between symbols and codewords while keeping all codewords unchanged. The proposed code is applied to the coding of \"macroblock types\" of MPEG and the experimental results show that it can achieve a 20%/spl sim/28% more savings of coded bits than MPEG. The hardware cost and operations of the proposed hardware architecture for the new code are significantly less when compared to conventional adaptive VLC. Hence, it is suitable for real-time coding systems, especially the video codec.<<ETX>>","PeriodicalId":110496,"journal":{"name":"Proceedings of TENCON '93.

As is well known for the detection of transient signals with unknown arrival times, there is no uniform tool because the detector performance usually depends on the signal representation. If all the signal components are similar, the present method, called the wavelet packet detection algorithm (WPDA), provides the possibility of detecting different arrival times correctly, even in the case that their waveforms overlap too much. The experiments show that WPDA can achieve satisfactory performance.<<ETX>>","PeriodicalId":110496,"journal":{"name":"Proceedings of TENCON '93.

Quadtree coded by breadth first (breadth first quadtree) has the same compression ratio with the quadtree coded by depth first (depth first quadtree). In breadth first quadtree, nodes in high level and low level appear in level by level, not at random. This makes it better for operation efficiency, especially in geometric property operation (perimeter calculation, area calculation, search, object labelling, neighbor finding) which needs long operation time. In this paper we show the advantage of breadth first quadtree by the worst case analysis and the general case analysis.<<ETX>>","PeriodicalId":110496,"journal":{"name":"Proceedings of TENCON '93.
