| Full name | ISO/IEC BIIF Profile BPJ2K01.00 -- Information technology - Computer Graphics and Image Processing - Registered Graphical Item - Class: BIIF Profile - Version 01.00 (2004) (formal name); JPEG 2000 BIIF Profile (common name) |
|---|---|
| Description |
Implementation of JPEG 2000 Core Coding (Part 1) that constrains the use of variables in the specification and has been designed to support NATO and U.S. military applications. A number of recommendations are outlined in the specification (pp. 20-21), including but not limited to:
Full representation of multispectral imagery (e.g., from satellites) requires the use of features of J2K_EXT, and extended BIIF-related profiling is anticipated. Additional general information about JPEG 2000 profiles is provided in the Notes to J2K_C Notes. |

| Normal rendering | See J2K_C |
| Clarity (high image resolution) | See J2K_C. Use of the lossless option in this profile will provide the greatest clarity. |
| Color maintenance | See J2K_C |
| Support for vector graphics, including graphic effects and typography | See JP2_FF |
| Support for multispectral bands | The specification states that the profile "is intended for the compression of literal imagery . . .[including] Multispectral . . . . It is expected that the multiple component transform framework from JPEG 2000 Part 2 (ISO/IEC 15444-2) will be included when the requirements for Hyperspectral imagery are established." |

| General | The following pertains to the synchronization of U.S. military standards with the BIIF profile: "The BPJ2K01.10 is the profile for the JPEG 2000 compression of digital imagery, incorporating the compressed digital imagery into NSIF files, and exchanging them within the user community. STANAG 4545 and (U.S.) MIL-STD-2500C are specific user community documents used for implementing the NSIF01.01 BIIF Profile and now, the BPJ2K Profile." (Web page consulted July 1, 2011.) The specification makes frequent use of these acronyms: NIMA, National Imagery and Mapping Agency (now the National Geospatial-Intelligence Agency [NGA]); NITF, National Imagery Transmission Format; NITFS, National Imagery Transmission Format Standard; NPJE, NSIF Preferred JPEG 2000 Encoding; and NSIF, NATO Secondary Image Format. |
