Abstract
A blocking artifact detection method is provided. The method, which is applied to a video encoder, includes: detecting, based on a sum of pixel differences between each coding unit in a current coding tree unit and its adjacent coding unit, whether the coding unit and the adjacent coding unit meet an edge detection condition; in response to determining that a coding unit and its adjacent coding unit meet the edge detection condition, determining, based on information about the coding unit, image regions of an original image corresponding to the coding unit and the adjacent coding unit; detecting whether the image regions meet the edge detection condition; and determining, in response to determining that the image regions do not meet the edge detection condition, that there is a blocking artifact between the coding unit and the adjacent coding unit. This implementation improves the accuracy of blocking artifact detection.
