Abstract:
1. A system for reducing blocking artifacts, the system comprising: a deblocking module comprising a luma deblocking filter and a chroma deblocking filter configured to filter an edge between adjacent blocks associated with video data, wherein a block of the adjacent blocks corresponds to one of a prediction block and a transform block and wherein the edge is filtered by the chroma deblocking filter based on the at least one filter coefficient on determining the adjacent blocks to be associated with the blocking artifacts and the boundary strength to be non-zero value; and a processing module communicatively associated with the deblocking module, the processing module operable to configure at least one filter coefficient corresponding to the chroma deblocking filter based on one or more filter coefficients corresponding to the luma deblocking filter, and the processing module being configured to cause the chroma deblocking filter to filter the edge based on the at least one filter coefficient, wherein the one or more filter coefficients correspond to a filtering mode of the luma deblocking filter associated with modifying fewer pixel values of pixels associated with at least one of the adjacent blocks as compared to one or more remaining filtering modes of the luma deblocking filter.
