Journal ArticleDOI
Fast HEVC Encoding Decisions Using Data Mining
TL;DR: Extensive experiments and comparisons demonstrate that the proposed early termination schemes achieve the best rate-distortion-complexity tradeoffs among all the compared works.
Proceedings Article
Fast HEVC intra prediction mode decision based on EDGE direction information
TL;DR: A fast intra prediction mode decision algorithm, which instead of taking into account only the modes of the neighbor PUs (prediction units) uses edge information of the current PU to choose a reduced set of directions from which the best prediction mode (direction) is finally selected.
Journal ArticleDOI
Retinal image quality assessment using generic image quality indicators
TL;DR: A retinal image gradability assessment algorithm based on the fusion of generic image quality indicators is introduced demonstrating very good performance and confirming the usability of the solution in an ambulatory application environment.
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.

TL;DR: A quality evaluation study of point cloud codecs that have been recently standardised by the MPEG committee is presented, confirming the superior compression performance of the MPEG V-PCC, when compared to MPEG G-P CC, in the case of static contents.
