About JPEG2000 file
JPEG 2000 is a wavelet-based image compression standard. The standardized filename extensions are .jpx for the extended part-2 specifications and .jp2 for ISO/IEC 15444-1 conforming files.
JPEG2000 can operate at higher compression ratios without generating the characteristic 'blocky and blurry' artifacts of the original DCT-based JPEG standard and allows more sophisticated progressive downloads. JPEG 2000 has some advantages over the ordinary JPEG standard: superior compression performance, multiple resolution representation, progressive transmission by pixel and resolution accuracy, lossless and lossy compression, random codestream access and processing, errors resilience, sequential buildup capability, flexible file format. The artifacts of JPEG 2000 look different from those of JPEG, have a smaller effect on the image and are visible only at higher compression levels. |
