چکیده

3D subband video coding provides an elegant fulldimensional solution for scalable video coding. However, due to the Motion-Compensated Temporal Filtering (MCTF) with open-loop structure and no good rate distortion optimization trade-off between the texture coding and overhead coding of the corresponding mode and motion vectors within narrow bandwidth, its performance is unsatisfactory at low bit-rates. On the other hand, video data below a certain spatial, temporal or SNR resolution are not required in most applications of scalable video coding. The introduction of a base layer in three-dimensional subband scalable video coding scheme can provide a lot of advantages such as close-loop temporal prediction, inloop filter and rate-distortion optimization without any constraint occurred in pure 3D subband codec and also compatibility with existing video compression standards. This paper presents the architectures about how to efficiently incorporate base layer codec MPEG-4 AVC into 3D subband video coding.

Architectures of Incorporating Mpeg-4 Avc into Three-dimensional Wavelet Video Coding

3D wavelet video coding provides an elegant fulldimensional solution for scalable video coding.

Low complexity bit-plane entropy coding for 3-D DWT based video compression

This paper is dedicated to entropy coding for scalable video compression based on three-dimensional discrete wavelet transform (3-D DWT). A new simple bit-plane entropy coding of wavelet subband matrices is proposed. Practical results show that 3-D DWT video codec with proposed entropy coding allows to increase the encoding speed 2-3 times for the same quality level in comparison with x.264 cod...

Three-Dimensional Subband Scalable Video Coding Embedded with H.264/AVC Codec

This paper presents a new Base Layer coding scheme which introduces the rate-distortion optimization mode decision into hierarchical-fashion B-picture coding with open-loop structure. It can not only achieve high coding performance for Base Layer bit-rate point and meanwhile, but the scheme also keep the strong correlation between Base Layer and Enhancement Layer implemented by 3D subband scala...

Joint Video Team (jvt) of Iso/iec Mpeg & Itu-t Vceg (iso/iec Jtc1/sc29/wg11 and Itu-t Sg16 Q.6)

This document contains a description of an SNR-scalable extension of H.264/AVC [1]. To achieve an efficient SNR-scalable bitstream representation of a video sequence, the temporal dependency between pictures is coded using an open-loop subband approach. In this codec, most components of H.264/AVC are used as specified in the standard while only a few have been adjusted to the subband coding str...

An Adaptive Scan of High Frequency Subbands of Dyadic Intra Frame in MPEG4-AVC/H.264 Scalable Video Coding

This paper develops a new adaptive scanning methodology for intra frame scalable coding framework based on a subband/wavelet(DWTSB) coding approach for MPEG-4 AVC/H.264 scalable video coding (SVC). It attempts to take advantage of the prior knowledge of the frequencies which are present in different higher frequency subbands. We propose dyadic intra frame coding method with adaptive scan (DWTSB...
