An Adaptive Coefficient Scanning Scheme for Inter-prediction Coding
نویسندگان
چکیده
Transform coefficient scan is an important procedure of video coding. In video coding standards such as MPEG2, H.264 and AVS, there are zig-zag scan for frame coding and field scan for field coding. In this paper, a novel adaptive coefficient scanning scheme for inter-prediction coding is proposed. This scheme includes scanning pattern generation based on DCT energy statistical calculation and macroblock level Rate-Distortion Optimized scanning pattern selection. Simulation results show that the proposed adaptive coefficient scanning scheme can achieve significant compression improvement.

Adaptive Scan Pattern for Quantized Coefficients in Intra Coding of H.264
Various scanning algorithms have been proposed to enhance the performance of intra prediction of H.264 codec. In this paper, an adaptive scanning scheme is proposed to achieve the entropy coding gain in intra coding, where scanning patterns are updated based on the probabilistic distribution of quantized coefficients of previous macroblocks so that the consecutive zeros are located at the rear ...
متن کاملAn Efficient Combined Inter and Intra Prediction Scheme for Video Coding
Inter prediction and intra prediction are utilized by video coding standard H.264/AVC to exploit the temporal and spatial redundancy respectively. To further improve coding efficiency, combined inter and intra prediction was proposed to produce more accurate prediction signal. However, these methods suffer from either high computation or limited improvement. In this paper we present an efficien...
متن کاملA novel coefficient scanning scheme for directional spatial prediction-based image compression
Spatial prediction is a promising technique for image coding. For example, the coming AVC/H.264 standard adopts directional spatial prediction in the Intra frame coding. Similar to the traditional DCT-based image coding schemes, it still scan the transform coefficients in a zigzag order, which is inefficient for coding the residual signals predicted from the different directions. To tackle this...

H.264 [1] and AVS [2] are the emerging state-of-art video coding standards, in which the block-based hybrid coding framework is employed. DCT or its approximation such as Integer Cosine Transform (ICT) is the centerpiece for signal decorrelation and energy compaction. After DCT, the transform coefficients are quantized and scanned into one-dimensional (1-D) signals, named run-level pairs. The k...

Lifting is an efficient algorithm to implement the discrete wavelet transform in order to overcome the drawbacks of the conventional wavelet transform that does not provide a compact representation of edges which are not in horizontal and vertical directions. The lifting scheme provides a general and flexible tool for the construction of wavelet decompositions and perfect reconstruction filter ...
