PECSI utilizes important human perceptual characteristics during image encoding stages (e.g. downsampling and quantization) and image decoding stages (e.g. upsampling and deblocking) to find a better balance between image compression and the perceptual quality of an image. The proposed framework is computationally efficient and easy to integrate into existing block-based still image compression standards. Experimental results show that the PECSI framework provides improved perceptual quality at the same compression rate as existing still image compression methods. Alternatively, the framework can be used to achieve higher compression ratios while maintaining the same level of perceptual quality. <\/jats:p>","DOI":"10.1142\/s0219467809003551","type":"journal-article","created":{"date-parts":[[2009,10,26]],"date-time":"2009-10-26T06:57:03Z","timestamp":1256540223000},"page":"511-529","source":"Crossref","is-referenced-by-count":0,"title":["PECSI: A PRACTICAL PERCEPTUALLY-ENHANCED COMPRESSION FRAMEWORK FOR STILL IMAGES"],"prefix":"10.1142","volume":"09","author":[{"given":"ALEXANDER","family":"WONG","sequence":"first","affiliation":[{"name":"Department of Systems Design Engineering, University of Waterloo, 200 University Ave. West, Waterloo, Ontario N2L3G1, Canada"}]}],"member":"219","published-online":{"date-parts":[[2011,11,20]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1145\/103085.103089"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.1109\/83.334991"},{"key":"rf4","first-page":"1096","volume":"2","author":"Liu S.","journal-title":"IEEE Proceedings of Southeastcon"},{"key":"rf16","first-page":"152","volume":"12","author":"Xue K.","journal-title":"Journal of Electronic Imaging"},{"key":"rf17","first-page":"1","volume":"14","author":"Temizel A.","journal-title":"Journal of Electronic Imaging"},{"key":"rf18","doi-asserted-by":"publisher","DOI":"10.1109\/83.392332"},{"key":"rf19","doi-asserted-by":"publisher","DOI":"10.1109\/TCSVT.2002.804881"},{"key":"rf20","doi-asserted-by":"publisher","DOI":"10.1109\/76.678636"},{"key":"rf22","doi-asserted-by":"publisher","DOI":"10.1109\/97.659544"},{"key":"rf23","doi-asserted-by":"publisher","DOI":"10.1109\/76.564123"},{"key":"rf24","first-page":"298","volume":"5","author":"O'Rourke T.","journal-title":"IEEE Transactions on Circuits and Systems for Video Technology"},{"key":"rf26","doi-asserted-by":"publisher","DOI":"10.1023\/A:1008167430544"},{"key":"rf28","doi-asserted-by":"publisher","DOI":"10.1109\/LSP.2003.817179"},{"key":"rf29","doi-asserted-by":"publisher","DOI":"10.1109\/TIT.1974.1055250"},{"key":"rf30","doi-asserted-by":"publisher","DOI":"10.1038\/302419a0"},{"key":"rf31","unstructured":"M.\u00a0Livingstone, Vision and Art: The Biology of Seeing (Harry N.
