New Trends in Very Low Bit Rate Video Coding — An Overview

摘要: Publisher Summary This chapter provides an overview of existing approaches that target very low bit rates. It gives a review high-compression image-coding techniques and overviews video coding aimed at These have been classified into four classes: waveform, object-based, model-based, fractal-based techniques. Then, pre- postprocessing the visual information is overviewed in this chapter. Existing products market are described finally, conclusions drawn last section. clear developed for still pictures can be either extended to 3D signals or hybrid approach defined based on motion compensation. Waveform-based prove efficient when proper low-bit-rate-oriented features added. However, other specifically designed bit-rate applications show significant promise, namely object-oriented,
