A Video Coding Technique Using Octagonal Motion Search and BTC-PF Method for Fast Reconstruction

摘要

Video coding systems includes motion compensation, frequency transformation, quantization, and lossless or entropy coding. For applications like, video playback, the time complexity of the decoder is an important issue. Motion estimation (ME) is the most time constraint modules of video coding technique, and the frequency transformation/inverse transformation also consume a considerable amount of time. For real-time application, decoder has to be fast enough to reconstruct the frames from transmitted data; but the most time constraint module of the decoder is the inverse transformation. In this paper, a fast motion estimation algorithm is used and in residual frame coding purpose, a fast method based on block truncation coding with pattern fitting concept is employed. Proposed video coding method is a fast one with a good quality at the reasonable bit-rate, also the decoder is much faster.
