Its aim is to obtain high\u2010compression factors by exploiting the characteristics of a second\u2010generation method (i.e., polynomial approximation) in suitable scene areas, while achieving higher fidelity, where required by the local image characteristics, through a first\u2010generation technique (i.e., vector quantization).<\/jats:p><jats:p>Such a region\u2010driven hybrid approach performs the integration by utilizing a control image (resulting from the detection of areas characterized by high spatial frequencies) that drives the segmentation and approximation processes.<\/jats:p><jats:p>The results obtained on a variety of natural color images are quite satisfactory. The visual quality of the reconstructed images is, in general, very good, and SNR is kept within an acceptable range. Moreover, the bit rate obtained is always below 0.15 bit\/pixel (bit\/pixel), with peak values of 0.07 bit\/pixel.<\/jats:p>","DOI":"10.1002\/ett.4460040214","type":"journal-article","created":{"date-parts":[[2008,9,12]],"date-time":"2008-09-12T13:44:37Z","timestamp":1221227077000},"page":"183-191","source":"Crossref","is-referenced-by-count":1,"title":["Data Compression for Image Archiving Applications"],"prefix":"10.1002","volume":"4","author":[{"given":"Francesco G.
