This paper presents a strategy that efficiently allocates the limited resource and still maintains the coding performance for the spatial scalability of H.264/SVC. An integrated computation-scalable algorithm is proposed based on mode decision and adaptive search range. The RD-cost of the base layer is used as the priority to decide the mode in the enhancement layer, and the motion vector difference...
The state-of-the-art video coding standard H.264 provides efficient compression and rate control for various video applications. However, by using the current rate control mechanism of H.264 for a video streaming, the output end users would experience a serious video distortion when a data burst happens in the input video. In order to ensure the output video quality and maintain a stable output bit...
H.264 is a new video coding standard which contains some novel coding functions and provides more coding efficiency than previous standards. However, video streams are sensitive to channel errors that often degrade the visual quality of the decoded sequence, not only corrupt the current frame but also propagate to subsequent frames. In order to solve this problem, the error concealment in the decoder...
In this paper, a fast block-based motion estimation algorithm which combines the finite-state side match concept for H.264 video coding standard is proposed. The proposed algorithm performs the side matching for each candidate position within the search window and chooses several positions which have least side match sum of absolute difference to form a finite-state motion vector set. Afterwards,...
In this paper, a fast motion estimation algorithm for variable block-size by using a motion vector merging procedure is proposed for H.264. The motion vectors of adjacent small blocks are merged to predict the motion vectors of larger blocks for reducing the computation. Experimental results show that our proposed method has lower computational complexity than full search, fast full search and fast...
