Abstract:

This paper discusses the implementation of a very low bit rate video codec (coder-decoder) which achieves a bit rate of as low as about 25 Kbps for test sequences having frame rate of 7 fps and frame size of 256×256 pixels. We have employed techniques like Comer matching and tracking for motion prediction that is instrumental in reducing the bitrate and the optimized rainfalling watershed algorithm results in better and faster image segmentation. We also discuss the results of incorporating Smart (yet simple and flexible) Error Resiliency features like Reversible Variable Length Coding and Resynchronization Markers into out very low bit-rate video codec.
