Wavelet block-tree coding (WBTC) improves the image compression performance of set partitioning in hierarchical trees (SPIHT) at lower rates by efficiently encoding both inter- and intra-scale correlations. The use of auxiliary lists makes WBTC undesirable for hardware implementation as it needs a lot of memory management due to exponential increase of nodes on each pass. The proposed coder named as hierarchical listless block-tree DTT (HLBT_DTT) that combines discrete Tchebichef transform (DTT) with MLBTC exhibits compression performance significantly higher than most of the DCT-based embedded coders and comparable with JPEG 2000, especially at lower bit rates. Further, HLBT_DTT requires only 10% of memory than that of DCT-based SPIHT\/WBTC coders. <\/jats:p>","DOI":"10.1142\/s0219467813500058","type":"journal-article","created":{"date-parts":[[2013,4,15]],"date-time":"2013-04-15T10:07:16Z","timestamp":1366020436000},"page":"1350005","source":"Crossref","is-referenced-by-count":3,"title":["LOW BIT RATE IMAGE COMPRESSION USING HIERARCHICAL LISTLESS BLOCK-TREE DTT ALGORITHM"],"prefix":"10.1142","volume":"13","author":[{"given":"RANJAN K.","family":"SENAPATI","sequence":"first","affiliation":[{"name":"Department of Electronics and Communication Engineering, National Institute of Technology, Rourkela, Orissa 769008, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"UMESH C.","family":"PATI","sequence":"additional","affiliation":[{"name":"Department of Electronics and Communication Engineering, National Institute of Technology, Rourkela, Orissa 769008, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"KAMALA K.","family":"MAHAPATRA","sequence":"additional","affiliation":[{"name":"Department of Electronics and Communication Engineering, National Institute of Technology, Rourkela, Orissa 769008, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2013,5,3]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1016\/S0923-5965(01)00025-X"},{"key":"rf2","first-page":"1158","volume":"9","author":"Shapiro J.
