X-ray image separation via coupled dictionary learning [PDF]

open access: yes, 2016
In support of art investigation, we propose a new source sepa- ration method that unmixes a single X-ray scan acquired from double-sided paintings. Unlike prior source separation meth- ods, which are based on statistical or structural incoherence of the ...

Exploiting MPEG-7 texture descriptors for fast H.264 mode decision [PDF]

open access: yes, 2008
A novel technique for exploring the use of indexing metadata in improving coding efficiency is proposed in this paper. The technique uses an MPEG-7 descriptor as the basis for a fast mode decision algorithm for H.264/AVC encoders.
