Regression Wavelet Analysis for Near-Lossless Remote Sensing Data Compression Álvarez Cortés, Sara Serra-Sagristà, Joan Bartrina-Rapesta, Joan Marcellin, Michael W. Lossless and near-lossless compression Pyramidal multiresolution scheme Regression wavelet analysis Remote sensing data compression Altres ajuts: Universitat Autònoma de Barcelona under Grant UAB-PIF-472/2015 Regression wavelet analysis (RWA) is one of the current state-of-the-art lossless compression techniques for remote sensing data. This article presents the first regression-based near-lossless compression method. It is built upon RWA, a quantizer, and a feedback loop to compensate the quantization error. Our near-lossless RWA (NLRWA) proposal can be followed by any entropy coding technique. Here, the NLRWA is coupled with a bitplane-based coder that supports progressive decoding. This successfully enables gradual quality refinement and lossless and near-lossless recovery. A smart strategy for selecting the NLRWA quantization steps is also included. Experimental results show that the proposed scheme outperforms the state-of-the-art lossless and the near-lossless compression methods in terms of compression ratios and quality retrieval. 2020 Article https://ddd.uab.cat/record/215773 urn:10.1109/TGRS.2019.2940553 urn:oai:ddd.uab.cat:215773 urn:articleid:15580644v58n2p790 urn:scopus_id:85078744720 urn:wos_id:000510710600003 urn:oai:egreta.uab.cat:publications/1f87fc69-ed05-4dad-96f5-0d77d59ad5dd eng Agencia Estatal de Investigación RTI2018-095287-B-I00 Agència de Gestió d'Ajuts Universitaris i de Recerca 2017/SGR-463 IEEE transactions on geoscience and remote sensing ; Vol. 58, Issue 2 (February 2020), p. 790-798 open access Aquest material està protegit per drets d'autor i/o drets afins.
