| Abstract: | In this paper we propose three algorithms for low bit-rate (LBR) video transmission, namely Simple Dynamic Profiling (Simple DP), Minimum Dynamic Profiling (Minimum DP) and Mean Dynamic Profiling (Mean DP). These techniques can be used in conjunction with other low bit rate techniques. Many of the techniques available for low bit rate video applications will either require lot of hardware resources or take advantage of the powerful computer platform that is used for their software implementation. On the other hand, the proposed algorithms are devised targeting hardware implementation for systems with limited hardware resources. When compared to coarse quantization technique, the new techniques not only achieve better compression ratio (twice that of the coarse quantization), but also result in better PSNR results (27 db for the coarse quantization versus 33 to 36 db for the new techniques). | ||
