Dynamic profiling algorithms for low bit rate video applications

We propose three algorithms for low bit-rate (LBR) video transmission, namely simple dynamic profiling (SimpleDP), minimum dynamic profiling (MinimumDP) and mean dynamic profiling (MeanDP). These techniques can be used in conjunction with other low bit rate techniques. Many of the techniques available for low bit rate video applications either require a 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 to target hardware implementation for systems with limited hardware resources. When compared to the coarse quantization technique, the new techniques not only achieve better compression ratio (twice that of coarse quantization), but also result in better PSNR results (27 dB for coarse quantization versus 33 to 36 dB for the new techniques).
