Abstract :
A low cost noise reduction technology for compressed video such as the mosquito noise and the block noise has been developed. The authors characterized the length of filter taps for block and mosquito noise and proposed the memory sharing architecture for both types of noise detection. The architecture contributes the reduction of line memories required for buffering filtering data in a noise reduction pipeline.
