    9. Prepared by Kate Grant, JTC1 liaison to IEC TC100 Resolution 43 – Restructuring of JPEG Digital imaging systems and JPEG XR WG 1 is recommending the restructuring of JPEG DI and JPEG XR into two work items. Under this recommendation JPEG XR will continue under the current work number ISO 29199 (changing the name to JPEG XR) and a new work item for JPEG DI will be introduced. WG 1 has identified possible sub-divisions of JPEG DI (currently the System Overview is in WD stage for JPEG DI Part 1) and is requesting comments on these recommendations and possible new work items. The following are possible sub-divisions of the JPEG DI standard: • Systems overview (Technical Report –TR) • JPEG family of compression standards (TR) • File Format/Metadata (TR) • JPEG DI Interactive Protocols (client/server) (IS) • JPEG DI Security (IS) • Evaluation methodologies for assessing compression technology (TR) • JPEG DI Application profiles (TR) WG 1 requests National Bodies to comment on the proposed restructuring of the JPEG DI and JPEG XR standards. Specifically, WG 1 requests each National Body to comment on the recommended work items, new work items that should be considered in JPEG DI, National Body support for the new work items, and recommendations for working

    12. Prepared by Kate Grant, JTC1 liaison to IEC TC100 Resolution 56 – WG 1 affirmation of IP guideline statement submission WG 1 re-affirms its support for its IP guideline statement first approved at the 16th WG 1 Seoul Meeting, March 1999. “WG 1 requires all participants within all National Bodies to disclose and identify any and all patent rights and the specific technologies within the Verification Model to which they apply. Further, WG 1 requires this disclosure and identification at the time of submission of technology for VM consideration if submitted by the patent holder or no later than one meeting after submission of technology if the technology is not submitted by the patent holder. Further, WG 1 requires that the form contained in WG 1 N1267 be completed as part of this disclosure. This request is in accordance with Common Patent Policy for ITU-T/ITU-R/ISO/IEC, clause 3.” The relevant ISO/IEC directives are contained in the integration group report, WG1N1262.

    13. Prepared by Kate Grant, JTC1 liaison to IEC TC100 Resolution 57 – WG 1 affirmation of SC 29 resolution on IPR guidelines - 1 WG 1 complies with the Resolution 9: “SC 29 IPR Guidelines” of the 20th SC 29 Plenary Meeting, 2007-04-30/05-01, San Jose, USA “SC 29 affirms and supports Common Patent Policy for ITU-T/ITU-R/ISO/IEC that requires a party that submits a technology contribution for proposed inclusion in any SC 29 standard to disclose to the WG the existence of patents or published pending patent applications, hereafter referred to as "IP rights", of which the party is personally aware and which the party considers to cover any item of its contribution. "[Clause 3, Guidelines for Implementation of the Common Patent Policy for ITU-T/ITU-R/ISO/IEC] any party participating in the work of the Organizations should, from the outset, draw their attention to any known patent or to any known pending patent application, either their own or of other organizations."

    14. Prepared by Kate Grant, JTC1 liaison to IEC TC100 Resolution 57 – WG 1 affirmation of SC 29 resolution on IPR guidelines - 2 SC 29 affirms the Common Patent Policy for ITU-T/ITU-R/ISO/IEC of only considering for inclusion in a standard (unless the ISO Council authorizes an exception) technology that is either 1) free of IP rights, or 2) available to all implementers of the standard without a royalty or license fee and under other reasonable and non-discriminatory ("RAND") terms and conditions, or 3) available to all implementers of the standard for a reasonable royalty/license fee and under other RAND terms and conditions. Although royalty-bearing patented technologies may be included in SC 29 standards, SC 29 suggests to its WGs to promote, whenever possible, the inclusion of technologies that either do not require a patent license, or that only require a RAND license without a royalty or license fee. Additionally, SC 29 encourages disclosure by the IP rights holder of the type of licensing under which these IP rights will be made available for conforming implementations of ISO/IEC standards after final publication -- that is either 1) royalty/license fee-free and under other RAND terms and conditions, or 2) reasonable royalty/license fee and under other RAND terms and conditions. Negotiations regarding specific licensing terms and conditions are left to the parties concerned and are performed outside of SC 29. Further, SC 29 requires software and technology contained in any party's contribution to an SC 29 standard to be made available by such party to all members of the SC 29 WG developing such standard, on a royalty- and license fee-free basis, solely .

    17. Prepared by Kate Grant, JTC1 liaison to IEC TC100 Image Signature The ImageSignature descriptor provides a "fingerprint" to uniquely identify individual visual media items. It has no direct association with specific visual features. The ImageSignature descriptor (the signature) is robust (unchanging) across a wide range of common editing operations, but is sufficiently different for every item of "original" content to identify it uniquely and reliably – just like human fingerprints.

    18. Prepared by Kate Grant, JTC1 liaison to IEC TC100 Image Signature The descriptor is able to distinguish between two images which have similar content and two images which are the same The descriptor analyses lines and circles in an image to extract a 512 bit signature that is robust to common processing operations that may be performed on the image.

    19. Prepared by Kate Grant, JTC1 liaison to IEC TC100 Trace transform The Trace transform applies functionals over all of the lines in the image. A functional is a real-valued function on a vector space V, usually of functions. A line is parameterised by the distance d and the angle ? and points on the line by the parameter t. The result of applying a Trace transform is a 2D function. A further functional can then be applied to the columns of the Trace transform to give a vector of real numbers. This second functional is known as the diametrical functional and the resulting vector is known as the circus function. The properties of the circus function can be controlled by appropriate choices of the two different functionals (trace and diametrical). The trace-transform based technology was promoted from Working Draft to PDAM. (ISO/IEC 15938-3:2002/PDAM 3)

    20. Prepared by Kate Grant, JTC1 liaison to IEC TC100 VCE-6 – Image Signature (Visual identifier) Experiment Conditions The images are selected from the CD-ROMs "Art Explosion 800000" by Nova, available at: http://www.amazon.co.uk/Nova-ARW-Art-Explosion-800000/dp/B0001XWNSS/ref=pd_bbs_sr_1/203-3503298-4948756?ie=UTF8&s=software&qid=1183552443&sr=8-1 The experiment consists of two tests, one for independence and for robustness

    21. Prepared by Kate Grant, JTC1 liaison to IEC TC100 VCE-6 – Image Signature (Visual identifier) Independence Test A large database (N˜135k images in List A) of different (independent) images shall be used to determine the parameters (e.g. a threshold) for each algorithm corresponding to the required maximum false positive rates. The maximum rate of false positive matches shall be: For basic modifications only: =0.05 ppm (parts per million) For all modifications: =10.0 ppm (parts per million) All possible pairs of images in the database shall be used for this purpose (excluding self-comparison); the number of comparisons is therefore (Nx(N-1)/2).

    22. Prepared by Kate Grant, JTC1 liaison to IEC TC100 VCE-6 – Image Signature (Visual identifier) Robustness Test: Each algorithm is tested for robustness to various types of modifications and its success ratio is determined in each category (see Table 1). For this test a second database of M (=10k) “original” images is created according to the List B. For each “original” image from the B-list, 41 modified (transformed) versions are created, using the transformation parameters from Table 1. Software to generate the transformed images is available for download from ftp://image.dgu.ac.kr

    23. Prepared by Kate Grant, JTC1 liaison to IEC TC100 VCE-6 – Image Signature (Visual identifier) The basic modifications are: Brightness change Color to monochrome conversion JPEG compression with varying quality factors Color reduction Gaussian Noise Histogram equalization Image enhancement via Auto-level Blur Scaling Rotation by angle 90°, 180° and 270°. Flip The additional complex modifications are: Rotation Translation Aspect ratio change Crop Skew Perspective Combination of cropping, translation and scaling

    24. Prepared by Kate Grant, JTC1 liaison to IEC TC100 VCE-7: Video Signature It was reported that existing MPEG-7 visual descriptors give limited performance in the role of video signatures; especially when text is overlaid on video. This CE explores what technologies, if any, are suitable for the task of identification of video-clips (i.e. video-clip signatures). The main focus is on accuracy and robustness of identification. (Note: one of application of the video identifiers is to detect replicas of a video material).

    25. Prepared by Kate Grant, JTC1 liaison to IEC TC100 RVC: Reconfigurable Video Coding MPEG-B related core experiment (8 contributions) Automatic generation of parser – VLD decoding, Btype generation Compressed bitstream syntax (CDDL) MPEG-C related contributions (4 contributions) AVC interlaced coding FUs VLD decoding FUs T oken classification MPEG-2 FUs There was also one exploration contribution on an AVS parser FU, and one contribution on RVC support tools – status of CAL2C generation tool. CDs for both parts (23001-4 and 23002-4) will be finally edited and released at the end of the week. These will be as approved at the last meeting, not including compact binary description. FCD is expected in April.

    26. Prepared by Kate Grant, JTC1 liaison to IEC TC100 Free-viewpoint TV The focus of the next phase of the FTV work will be “3D TV” supporting N-view displays (various types) where only a low number of views (say up to three) and depth map is encoded. Test sequences will be designed accordingly, with a parallel camera set-up, and with rectification most probably being necessary. Test sequences would be provided in rectified, illumination and colour compensated form. The maximum angle between left and right will be around 20 degrees (today’s displays 10 degrees). A new updated call for test sequences and depth estimation software will be issued, including high level description of the scope of FTV. An investigation into depth estimation and interpolation performance will be performed in an exploration experiment, based on the algorithm proposals submitted. This should bring evidence about: Whether sufficiently food depth estimation algorithms are available What level of quality can be achieved in view synthesis, and whether PSNR comparison against original views is useful Determine the suitability of the test sequences already available and subsequently provided, for the purposes of the up-coming call for proposals.

    27. Prepared by Kate Grant, JTC1 liaison to IEC TC100 JVT Update The new edition of 14496-10:200x, including the Professional profiles and SVC is due to be completed in October. The conformance and software amendments for the Professional Profiles and SVC are in progress, reaching FPDAM at 83rd meeting. A corrigendum is underway, including corrections to SVC. The other current work taking place is on the following topics: Multi-view video coding (MVC: 14496-10:200X/Amd.1) Study of benefit for possible extension to SVC to support bit depth scalability There are other proposals relating to SEI messages to support slicing and enhancements to coding efficiency

    28. Prepared by Kate Grant, JTC1 liaison to IEC TC100 SVC verification tests N9577 Report on SVC Verification tests Wide variety of test scenarios for all three profiles Including teleconferencing, internet broadcast, HD broadcast, production applications The results indicate that with at most a penalty of 10% of bit rate, scalability functionality can be supported There is a very clear advantage over simulcast Conclude that the challenge of scalable video coding has finally been met Evidence that this standard is useful in the market and may quickly be taken up

    29. Prepared by Kate Grant, JTC1 liaison to IEC TC100 Video Surveillance (VS-AF) ISO/IEC 23000 (also known as “MPEG-A”) is an MPEG standard that supports a fast track to standardization by selecting readily tested and verified tools taken from the MPEG body of standards and combining them to form an AF (Application Format). If a needed piece of technology is not provided within MPEG, then additional technologies originating from other organizations can be included by reference in order to facilitate the envisioned AF. The Video Surveillance AF is a file format designed to provide for a first level of interoperability for video-based surveillance systems. The file format provides the overall structure for storing video content and associated meta-data in a single file It contains MPEG-4 AVC baseline profile video and associated MPEG-7 meta-data. Usage of other coded video formats will be assisted. Liaison sent to: IEC TC 9 WG43
