Abstract
Methods and systems for denoising embedded digital video decoding. Prediction and residue block of a current frame are obtained from motion vector. Variance of residue block is calculated using prior reference blocks, and a causal temporal linear minimum square error estimator is used to calculate a filter coefficient. The residue block is modified using the filter coefficient, and an output digital bitstream of blocks of pixels of the current frame is produced using the modified residue block and prior denoised prediction value of prior frames.
