Wavelets, image coding algorithms, multimedia processing.


With the increasing use of multimedia technologies, image compression requires higher performance as well as new features. To address this needs a new ISO/IEC JPEG2000 image coding standard has been developed. Lossless and lossy compression, progressive transmission and region-of-interest coding are vital new features based on advanced multiresolution techniques: integer wavelets, spatially segmented and line-based wavelet transforms, trellis quantization, binary arithmetic entropy coding and rate-distortion optimization. A JPEG2000 development of wavelet technology is reviewed in the paper, along with comparative analysis of performances and functionalities.
