Estimating the term…
A method, medium, and system reducing block noise of a digital image, including an encoding/decoding method, medium, and system. The method of reducing block noise of a digital image includes calculating a value of a boundary block that includes a boundary between two neighboring blocks, calculating the visibility of the boundary block by extracting specified characteristic values of the boundary block, classifying the boundary block according to a result of comparing the calculated visibility with a specified threshold value and whether the two neighboring blocks are corner blocks, and performing deblocking of the two neighboring blocks according to a result of classification.
A method of reducing block noise of a digital image, comprising:
At least one medium comprising computer readable code to control at least one processing element to implement at least one of a video encoding method and a decoding method, the method comprising:
A system to reduce block noise of a digital image, comprising:
At least one medium comprising computer readable code to control at least one processing element to implement a deblocking of two neighboring blocks according to a classification of a boundary block, as a boundary between the two neighboring blocks, based on a value of the boundary block and a comparing of a visibility of the boundary block with a specified threshold value and based upon a determination of whether the two neighboring blocks are corner blocks, wherein the visibility of the boundary block is calculated by extracting specified characteristic values of the boundary block.
