Perceptual Quality of H.264/avc Deblocking Filter
نویسنده
چکیده
The H.264/AVC standard defines an optional in-loop deblocking filter. The effect of this filter on subjective video quality is investigated. Filter settings preferred by users are recorded for a group of 82 users across a range of video sequences and coded bitrates. The results indicate two clear groupings of user preferences for lowand medium-activity sequences. There is no clear user preference when the sequence contains high motion and activity. The implications of these results for performance optimisation of H264/AVC CODECs are discussed.

Performance Evaluation of H.264/avc Deblocking Filter for 720p High Definition Video
High definition Video (HDV) is increasingly becoming common feature in video display devices as it provides superior level of details in comparison to standard video. Latest video compression standard, H.264/AVC can be used for storage and efficient transmission over network. However, blocking artifacts are introduced due to loss of correlation between blocks during compression process. H.264/A...

Finding out the better parameter set (OffsetA and OffsetB) for conducting the de-blocking process of H.264/AVC, is capable of improving visual quality, said eliminating the resultant blocking artifact. Identifying which edges belong to blocking regions relies on the perceptual judging process of human beings. In fact, this subjective assessment may not exactly match existing objective assessing...
متن کاملIn-Loop Deblocking Filter for JVT H.264/AVC
Presently block based transform coding using discrete cosine transform is the most popular approach for video compression. However, when the image is partitioned into blocks, it results is blocking artifacts due to lack of inter-correlation between blocks. These artifacts has much more annoying effect at low bit rates. This paper compares the performance of the in-loop deblocking filter of emer...
