About:
OpenJPH is a high-performance, open-source library implementing JPEG2000 Part-15 (JPH/HTJ2K). It provides advanced lossless and lossy image compression using the High Throughput JPEG2000 codec. This implementation is optimized for modern hardware, enabling efficient handling of large images and medical imaging data.
Key Features:
  • High Throughput JPEG2000 (HTJ2K) encoding and decoding
  • Optimized for CPU performance with SIMD instructions
  • Supports lossless and lossy compression modes
  • Compatible with standard JPEG2000 Part-1 files
Use Cases:
  • Medical imaging storage and transmission (DICOM)
  • High-resolution satellite and aerial imagery archiving
  • Digital cinema and professional media workflows
Alternatives:
  • openjpeg – OpenJPEG is the standard reference implementation of JPEG2000 (Part 1 & 2), while OpenJPH specifically focuses on the newer, faster HTJ2K standard.
  • kakadu – Kakadu is a highly optimized commercial JPEG2000 SDK, whereas OpenJPH provides a free and open-source alternative for HTJ2K.
