The Code4Lib Journal – Evaluating HTJ2K as a Drop-In Replacement for JPEG2000 with IIIF

JPEG2000 is a widely adopted open standard for images in cultural heritage, both for delivering access and for creating preservation files that are losslessly compressed. Recently, a new extension to JPEG2000 has been developed by the JPEG Committee: “High Throughput JPEG2000,” better known as HTJ2K. HTJ2K promises faster encoding and decoding speeds compared to traditional JPEG2000 Part-1, while requiring little or no changes to existing code and infrastructure. The IIIF community has completed a project to evaluate HTJ2K as a drop-in replacement for encoding JPEG2000 and to validate the expected improvements regarding speed and efficiency.
