Intra picture coding with planar representations
Jani Lainema,Kemal Ugur +1 more
TL;DR: This approach is found to provide up to 30 percent bitrate reductions in the case of natural imagery and it has also been adopted to the initial HEVC codec design by JCT-VC.

Scalable light field compression scheme using sparse reconstruction and restoration
TL;DR: A light field scalable compression scheme based on the sparsity of the angular Fourier transform of the light field, which shows a significant bit rate reduction in favor of the proposed compression method compared with a direct encoding of all the views with HEVC.
Proceedings ArticleDOI
HEVC selective encryption using transform skip signal and sign bin
TL;DR: Preliminary results show that the proposed selective video encryption method provides quality degradation up to -0.22 in SSIM score when compared to the conventional method, which is closed to the perfect dissimilarity with respect to the original video.
Journal ArticleDOI
Efficient H.264/AVC Video Coding with Adaptive Transforms
TL;DR: A novel content adaptive transform framework for the H.264/AVC-based video coding by utilizing pixel rearrangement to dynamically adjust the transform kernels to adapt to the video content and a spiral-scanning method is developed to reorder the transform coefficients for better entropy coding.

Content-Adaptive Motion Estimation Algorithm for Coarse-Grain SVC
Liquan Shen,Zhaoyang Zhang +1 more
TL;DR: This paper proposes a content-adaptive ME for SVC, including analyses of mode complexity and motion property to assist mode and motion searches, and shows that the proposed algorithm can significantly reduce the computational complexity of SVC while maintaining nearly the same rate distortion performance as the original encoder.
