REDUCING BLOCKINESS FOR CODECS

This abstract first appeared for US patent application 20250071345 titled 'REDUCING BLOCKINESS FOR CODECS

Original Abstract Submitted

disclosed is a method that includes receiving an image frame having a plurality of coded blocks, determining a prediction unit (pu) from the plurality of coded blocks, determining one or more motion compensation units arranged in an array within the pu, and applying a filter to one or more boundaries of the one or more motion compensation units. also disclosed is a method that includes receiving a reference frame that includes a reference block, determining a timing for deblocking a current block, performing motion compensation on the reference frame to obtain a predicted frame that includes a predicted block, performing reconstruction on the predicted frame to obtain a reconstructed frame that includes a reconstructed pu, and applying, at the timing for deblocking the current block, a deblocking filter based on one or more parameters to the reference block, the predicted block, or the reconstructed pu.
