- iberator 9mo agoNo. Jpg conpression sucks. Medical data should not be compressed loosely. PNG and TIFF for the win
- vrighter 9mo agounlike jpeg, jpeg-xl supports lossless compression too.
- nszceta 9mo agoThe original JPEG supports a lossless mode. JPEG-LL refers to the lossless mode of the original JPEG standard (ISO/IEC 10918-1 or ITU-T T.81), also known as JPEG Lossless, and not to be confused with JPEG-LS (ISO/IEC 14495-1, Transfer Syntax 1.2.840.10008.1.2.4.80), which offers better ratios and speed via LOCO-I algorithm. JPEG-LL is older and less efficient yet more widely implemented in legacy systems. The lossless mode in JPEG-XL is superior to all of those.
- tokyovigilante 9mo agoYes i am referring to lossless compression, and JPEG-XL also supports progressive lossless decoding. It also supports the 12 and 16-bit colour depths required for CT and DR.
