Abstract
A method and apparatus are provided for removing regularly occurring visible artifacts in decompressed video images. Firstly a decompressed video signal is received. This is filtered frame-by-frame to extract data related to the artifacts. The thus extracted data is then processed in a neural network processor which has been trained to identify the artifacts in order to produce data identifying their locations. The video signal is then corrected to reduce the effect of the thus identified artifacts.
