1. 1. Sparse representation of visual data for compression and compressed sensing

   Författare :Ehsan Miandji; Jonas Unger; Anders Ynnerman; Hendrik P. A. Lensch; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The ongoing advances in computational photography have introduced a range of new imaging techniques for capturing multidimensional visual data such as light fields, BRDFs, BTFs, and more. A key challenge inherent to such imaging techniques is the large amount of high dimensional visual data that is produced, often requiring GBs, or even TBs, of storage. LÄS MER
