A Novel Macro-Block Group Scheme of AVS Coding for Many-Core Processor
Macro-Block Group AVS Coding Many-Core Processor
2010/12/20
The slice-level parallelism is popular in parallel video coding. However, the quality loses greatly because the dependency between macro-blocks is broken, especially on many-core platforms. To address...
Super resolution technique was first proposed for enhancing the image resolution, and then it was expanded to video sequence for obtaining a higher resolution video from low resolution input. Recently...

Improved FFSBM Algorithm VLSI Architecture Variable
2010/12/15
The video coding standard H.264/AVC has adopted variable block size motion estimation to improve coding efficiency, which has brought heavy computation burden.The FFSBM (fast full search block matchin...
Robust moving object segmentation on H.264/AVS compressed video using the block-based MRF model
H.264/AVS compressed video the block-based MRF model
2010/12/15
Moving object segmentation in compressed domain plays an important role in many real-time applications, e.g. video indexing,video transcoding, video surveillance, etc. Because H.264/AVC is the up-to-d...
Moving Object Segmentation: A Block-based Moving Region Detection Approach
Moving Object Segmentation Block-based Moving Region Detection Approach
2010/12/14
This paper presents a novel block-based moving region detection algorithm to segment objects. The frame is first partitioned into homogeneous regions. Moving region is then determined by a voting proc...
