Research on underground wireless video encoding algorithm based on region of interest for interprediction

The low illumination and odious environment in the coal mine underground have greatly affected the quality of video image. Aimed at the specialty that the background is unchanged basically at coal mine underground wireless video monitoring point with foreground objects moving only, the inter-prediction algorithm based on region of interest is brought forward in the article. By simulating, the algorithm could greatly reduce the complexity of video encoding and encoding rate, while the quality of video basically keeping unchanged or even enhanced.
