Overview

ISO/IEC 29199-4:2010/Amd 1:2014 is an amendment to the international standard for the JPEG XR image coding system, specifically addressing Part 4 - Conformance testing. Published by ISO, this amendment provides additional conformance test streams to enhance interoperability and robustness of JPEG XR implementations. The update extends the original ISO/IEC 29199-4:2010 by introducing new test files that cover previously untested or new features within the JPEG XR codec, ensuring better compliance and quality assurance across software and hardware platforms.

Key Topics

  • Additional JPEG XR conformance test streams: The amendment introduces new test streams that cover features not fully tested before or newly introduced in the JPEG XR standard.
  • Support for enhanced features:
    • Red-blue not swapped flag - Tests images where the red and blue channels are ordered differently, improving verification of color channel handling.
    • DCLP-QP flag - Tests related to variable quantization options for improved image compression control.
    • Trim-flexbits - Validates decoder behavior in trimming flexbits, which impacts decoding precision.
    • Spatial rotation (SPATIAL_XFRM_SUBORDINATE) - Tests spatial transformation features in JPEG XR images, enhancing quality verification for rotated images.
  • Box-based file format tests: Incorporation of test streams supporting the JPEG 2000 box-based file format wrapper, extending compatibility with Rec. ITU-T T.802 and ISO/IEC 15444-2.
  • Extensive test file collections: Includes multiple reference file sets with a variety of bit depths, output color formats, and quantization parameters.

Applications

  • Software and hardware development: Developers of JPEG XR decoders and encoders can use these conformance test streams to validate implementation accuracy and compliance.
  • Quality assurance and interoperability testing: Organizations can ensure JPEG XR products meet international standards, reducing errors related to color format handling and image transformations.
  • Digital imaging and multimedia: Enhances reliability in applications such as digital photography, video streaming, medical imaging, and remote sensing which require high-quality, efficient image compression.
  • Research and standards development: Provides a foundation for further improvements in JPEG XR coding techniques and future versions of the standard.

Related Standards

  • ISO/IEC 29199-2: JPEG XR core coding system specification, directly related to the features tested in this amendment.
  • ITU-T Recommendation T.832: Equivalent recommendation aligned with JPEG XR image coding.
  • ISO/IEC 15444-2 (JPEG 2000 Part 2): Defines box-based file format wrappers extended by this amendment for JPEG XR codestream integration.
  • ITU-T Recommendation T.802: Related to JPEG 2000 file format, incorporating extensions tested in this amendment to support JPEG XR wrapped codestreams.

Summary

ISO/IEC 29199-4:2010/Amd 1:2014 enhances the JPEG XR conformance testing framework by adding comprehensive new test streams addressing advanced color handling, spatial transformations, and file format extensions. This amendment supports industry efforts to maintain high-quality and interoperable imaging applications leveraging JPEG XR technology. For developers and testing laboratories, these additional test sets are a crucial resource for ensuring that JPEG XR implementations meet rigorous international standards.

Summary
This minor enhancement of Rec. ITU.T T.834 | ISO/IEC 29199-4 extends and enhances the set of test
streams for Rec. ITU.T T.832 | ISO/IEC 29199-2 in two ways: First, additional test streams cover
features than had either not yet been tested in earlier revisions or did not exist in earlier versions in the
standard. Second, extensions made to Rec. ITU.T T.802 | ISO/IEC 15444-2 allow the wrapping of JPEG XR
codestreams in the JPEG 2000 file format, for which new reference streams are included.
Three new test streams cover the “red-blue not swapped” flag recently introduced in Rec. ITU.T T.832
| ISO/IEC 29199-2, and the DCLP-QP flag, which was not covered in earlier tests. The “trim-flexbits”
feature was only partially tested in earlier revisions of this Recommendation | International Standard,
and test streams for this have been added. An additional set of test streams covers the spatial rotation
feature of JPEG XR known as “SPATIAL_XFRM_SUBORDINATE”.
The second block of tests cover the new boxed-based file format introduced in AMD.3 of Rec. ITU-T T.802 |
ISO/IEC 15444-2.
The new set of test streams is not included as an electronic attachment to this text due to size constraints,
but is available at the following URL:
