چکیده
2. Pattern omission method Abstract: In this paper, we present the so-called scalable pattern omission method for a deblocking filter. This exploits specific characteristics of the human visual system. The baseline of our method is to reduce processing time of the deblocking filter. In the development of the H.264/AVC decoder, the processing Deblocking filter consumes the most computation resource. We proposed a scalable pattern omission method during filtering to decrease macroblocks that are filtered by the deblocking filter. Simulation result shows that our method can achieved performance enhancement ranging about 20% to 70% in the processing time. 2. 1 Method concept

Quality of Service (QoS) is the important criteria in the video processing in H.264/AVC Bit-streams. In this paper, the encryption based bit streams transmitted to improve the security of the bit streams. So the proposed system mainly considered reduction of the de-blocking filter effect in the Mean Square Estimation (MSE). The Correlation Motion (CM) based MSE estimation method derives elabora...
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...

The scalable extension to H.264/AVC defines a coding scheme that organizes data in such a way that starting from a base layer increased spatial, temporal and quality detail can be obtained by the addition of successive information layers. In the case of spatial scalability a fundamental operation is inter-layer prediction which due to the block based nature of the algorithm originates block-edg...
متن کاملParallel Deblocking Filter for H.264/AVC on the TILERA Many-Core Systems
For the purpose of accelerating deblocking filter, which accounts for a significant percentage of H.264/AVC decoding time, some studies use wavefront method to achieve the required performance on multi-core platforms. We study the problem under the context of many-core systems and present a new method to exploit the implicit parallelism. We apply our implementation to the deblocking filter of t...
