PICTools Medical Features

JPEG 2000

• File Format and Codestream – Part 1
  • Continuous tone compression (1-bit to 24-bit)
  • Provides lossy and lossless compression
• 3D Volumetric Encoding – Part 2
  • Compress and decompress in accordance with the DICOM standard
  • Supports both lossy and lossless modes, JPEG 2000 raw codestream, and JPX format
  • Supports 24-bit RGB, 8 to 16-bit grayscale
• Multithreading
  • User-configurable number of threads to optimize performance on multicore CPUs
• JPIP – Part 9
  • Design and build a JPEG 2000 JPIP implementation
  • Speed up network viewing of user selectable resolutions and areas of interest
  • Provides JPIP APIs for client and server, JPEG 2000 compliant compression and decompression, and JPIP request and receive
  • The PICTools JPIP libraries were used to create many of the image streams in the ISO Part 4 interoperability reference test suite
• Transcoder
  • Allows many operations without decompressing and recompressing images, eliminating generational loss
  • Change the number of layers, file size, compression rate, overall quality, convert lossless to lossy, re-encode for JPIP transmission, and extract encoded thumbnails

Lossless JPEG

• Addresses the medical industry’s need for non-destructive compression 
• Provides fast compression for video performance 
• Is ideal for cardiology and ultrasound applications
• Supports 24-bit RGB, 8 to 16-bit grayscale data

Lossy JPEG

• Complete control over luminance, chrominance, and subsampling compression parameters
• High-speed 1/4, 1/16, 1/64 thumbnail decompression support
• Enhanced decompression minimizes JPEG block artifacts
• CMYK, YUV, RGB, 8-bit, and 12-bit grayscale support

JPEG-LS

• Provides excellent lossless or constrained-loss compression performance
• Decompression support for non-standard, improperly compressed JLS images
• Supports single component 2 to 16-bit grayscale images
• Supports multiple component 24-bit (RGB) images

JPEG-XR

• Provides support for fully standards based JPEG XR
• Supports multiple subsampling settings, including familiar medical settings of 4:2:2 and 4:2:0 with cosited and centered options
• A still image compression algorithm for continuous tone photographic images
• Features lossy and lossless compression, multiple colorspaces, a wide dynamic range, and extensive metadata support
• Performance optimized

Medical Image Processing & Editing

• Overlap filter options
• Post processing filter strength settings
• Embedded orientation flags
• Metadata support
• Tiling
• Subband control
• Buffer to buffer image processing for maximum flexibility
• The high-performance API offers total control of image processing functions
