Spatial error concealment for H.264 using sequential directional interpolation
TL;DR: A novel spatial error concealment algorithm based on prediction modes of intra-blocks which are included in a H.264-coded stream and highly correlated to the direction of local edge within the block is proposed, preserving local edge continuity for more visually acceptable images.

An Optimized Backlight Local Dimming Algorithm for Edge-Lit LED Backlight LCDs
TL;DR: In this paper, an efficient optimized backlight local dimming method that minimizes power consumption under a given allowable distortion for liquid crystal displays with edge-lit light-emitting diode backlight is presented.

A VBR Video Encoding for Locally Consistent Picture Quality With Small Buffering Delay Under Limited Bandwidth
Hoonjae Lee,Sanghoon Sull +1 more
TL;DR: A frame-layer variable bit rate (VBR) video encoding method for maintaining locally consistent picture quality of an encoded video with small buffering delay is proposed, which can be used for a video on demand (VOD) system which streams an encode video file to a client device under limited bandwidth or a real-time streaming application allowing a small delay.

Model-Based Chemical Exchange Saturation Transfer MRI for Robust z-Spectrum Analysis
TL;DR: This paper introduces a novel, model-based chemical exchange saturation transfer (CEST) magnetic resonance imaging (MRI), in which asymmetric spectra of interest are directly estimated from complete or incomplete measurements by incorporating subspace-based spectral signal decomposition into the measurement model of CEST MRI for a robust z-spectrum analysis.
