Light field imaging coding: Performance assessment methodology and standards benchmarking
TL;DR: A compression performance assessment methodology is proposed and the compression performance of the direct, fully compatible usage of the main image coding standards available, notably JPEG, JPEG 2000, H.264/AVC Intra and HEVC Intra for a representative set of light field images are presented.

Recognizable or Not: Towards Image Semantic Quality Assessment for Compression
Dong Liu,Dandan Wang,Houqiang Li +2 more
TL;DR: This paper proposes a full-reference ISQA measure for image semantic quality assessment (ISQA), and performs subjective test about text recognition from compressed images, and observes that the measure has high consistency with subjective recognizability.

Temporal consistency enhancement on depth sequences
Deliang Fu,Zhao Yin,Lu Yu +2 more
TL;DR: Experiments demonstrate that the proposed depth filtering algorithm can effectively suppress transient depth errors and generate more stable depth sequences, resulting in notable temporal quality improvement of the synthesized views and higher coding efficiency on the depth sequences.

Depth Map Estimation for Free-Viewpoint Television and Virtual Navigation
TL;DR: In this paper, a new method of depth estimation, dedicated for free-viewpoint television (FTV) and virtual navigation (VN), is presented, where multiple arbitrarily positioned input views are simultaneously used to produce depth maps characterized by high inter-view and temporal consistencies.
