TLDR
A video content variation (VCV) feature is suggested to implement fast AGD method by using block-based classification before executing MCTF, which reduces about 67% of the operation time consumed on average as compared to the CE2.Abstract:
In order to concurrently provide different video services for diverse access devices, the scalable quality and complexity services in a single bit stream offered by H.264-based scalable video coding (H.264/SVC) has gained a lot of attentions recently. However, the motion-compensated temporal filtering (MCTF) structure consumes a large amount of operation time when combined with Core Experiment 2 (CE2), which implements adaptive GOP detection (AGD). In this paper, we suggest a video content variation (VCV) feature to implement fast AGD method by using block-based classification before executing MCTF. Based on the JSVM 7.0 software, the simulation results show that the proposed method reduces about 67% of the operation time consumed on average as compared to the CE2.read more

Adaptive GOP structure determination in hierarchical B picture coding for the extension of H.264/AVC
TL;DR: Experimental results show that the proposed adaptive GOP structure determination scheme can provide better PSNR performance compared to the highest GOP setting in the existing hierarchical B-picture coding of H.264/AVC.

Three-dimensional subband coding with motion compensation
TL;DR: The scheme is interpreted more generally, viewed as a motion-compensated short-time spectral analysis of video sequences, which can adapt to the quickness of changes.

TL;DR: This paper investigates various classification techniques, applied to subband coding of images, as a way of exploiting the nonstationary nature of image subbands and the trade-off between the classification gain and the amount of side information.

Scene-context-dependent reference-frame placement for MPEG video coding
TL;DR: The proposed MA-based adaptive reference frame-placement scheme outperforms the standard fixed-reference frame- Placement and adaptive schemes based on histogram of difference and can achieve from 2 to 13.9% savings in bits while maintaining similar quality.
