Light field HEVC-based image coding using locally linear embedding and self-similarity compensated prediction
Ricardo J. S. Monteiro,Luis F. R. Lucas,Caroline Conti,Paulo Nunes,Nuno M. M. Rodrigues,Sergio M. M. de Faria,Carla L. Pagliari,Eduardo A. B. da Silva,Luís Ducla Soares +8 more
TL;DR: This paper proposes the addition of two new prediction tools to the HEVC framework, to improve its coding efficiency and based on the local linear embedding-based prediction and the self-similarity compensated prediction.
Journal ArticleDOI
Lossless Compression of Medical Images Using 3-D Predictors
TL;DR: Experimental results demonstrate the efficiency of the 3-D-MRP algorithm for the compression of volumetric sets of medical images, achieving gains above 15% and 12% for 8- and 16-bit-depth contents, respectively, when compared with JPEG-LS, JPEG2000, CALIC, and HEVC, as well as other proposals based on the MRP algorithm.

Locally linear embedding-based prediction for 3D holoscopic image coding using HEVC
Luis F. R. Lucas,Caroline Conti,Paulo Nunes,Luís Ducla Soares,Nuno M. M. Rodrigues,Carla L. Pagliari,Eduardo A. B. da Silva,Sergio M. M. de Faria +7 more
TL;DR: Experimental results show the advantage of the proposed prediction for 3D holoscopic image coding, compared to the reference HEVC standard as well as previously presented approaches in this field.
Proceedings ArticleDOI
Intra-prediction for color image coding using YUV correlation
Luis F. R. Lucas,Nuno M. M. Rodrigues,Sergio M. M. de Faria,Eduardo A. B. da Silva,Murilo B. de Carvalho,Vitor Silva +5 more
TL;DR: It is shown that a chrominance component can be more efficiently predicted by using the reconstructed data from both the luminance and the remaining chrominance signal.
Journal ArticleDOI
Intra Predictive Depth Map Coding Using Flexible Block Partitioning
Luis F. R. Lucas,Krzysztof Wegner,Nuno M. M. Rodrigues,Carla L. Pagliari,Eduardo A. B. da Silva,Sergio M. M. de Faria +5 more
TL;DR: The experimental tests demonstrated the superior rate-distortion performance of PDC, with average bitrate savings of 6%, when compared with the current state-of-the-art intra depth map coding solution present in the 3D extension of a high-efficiency video coding (3D-HEVC) standard.
