摘要： A method and apparatus for detecting banding artifacts in digital images and video contents. The method operates to (i) find the locations of the banding artifacts, (ii) determine the strength of the banding artifact per block, and (iii) determine overall banding artifact strength per picture. The banding artifact detection and strength assignment is done by first finding areas that are prone to banding artifact and then considering the local characteristics of the area to reduce the false detection. The banding artifact strength of a picture is determined by considering the size and the strength of the artifact areas in this picture as well as the artifact strength in the neighboring pictures.

摘要： The present invention involves detecting dark noise artifacts in coded images and video. Locations of artifacts in compressed pictures are found. A strength of the artifact per block is determined as is an overall dark noise artifact strength for each picture. Artifact detection and strength assignment is performed by analyzing candidate areas that could be prone to this type of artifact. Multiple features such as block variance, color information, luminance levels and location of the artifact could be used in this process. Also, median filtering may be used on the identified areas to eliminate isolated areas. A final artifact parameter for each picture can be assessed based on the total number of blocks that are classified as dark noise and also the strength of each macroblock.
