Abstract
A noise reduction system and method for reducing unwanted noise in digital data is disclosed. The system and method includes a noise reduction module having a noise estimation and reduction submodule. The noise estimation and reduction submodule can be any suitable submodule for receiving compressed data, estimating the amount of noise added due to data compression, and using the estimate to reset false gray pixels, thereby producing new data with reduced halos.
