11、ation) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization t
12、o deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO a
13、nd IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by
14、 the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote.

16、 Amendment 3:2010 to CAN/CSA-ISO/IEC 15938-3-04ISO/IEC 15938-3:2002/Amd.3:2009(E) ISO/IEC 2009 All rights reserved 1Information technology Multimedia content description interface Part 3: Visual AMENDMENT 3: Image signature tools Page 1, Scope Replace 1.2 entirely with the following: 1.2 Overview of
17、 Visual Description Tools This part of ISO/IEC 15938 specifies tools for description of visual content, including still images, video and 3D models. These tools are defined by their syntax in DDL and binary representations and semantics associated with the syntactic elements. They enable description
18、 of the visual features of the visual material, such as color, texture, shape, motion, localization of the described objects in the image or video sequence and also unique and robust identification of visual material. An overview of the visual description tools is shown in Figure 1. The basic struct
19、ure description tools include five supporting tools of visual descriptions defined in clauses 6-11. They are categorized into two groups, descriptor containers and basic supporting tools. The former consists of three datatypes, GridLayout providing efficient representations of visual features on gri
20、ds, TimeSeries representing temporal arrays of several descriptions, GofGopFeature describes representative descriptions over video segment, and MultipleView describing a 3D object using several pictures captured from different view angles. The latter contains two tools, Spatial2DcoordinateSystem us
21、ed to specify the 2D coordinate system and TemporalInterpolation indicating the interpolation method between two samples on a time axis. The remaining description tools, except for the FaceRecognition and ImageSignature descriptors, are associated with visual features and are grouped into five featu
22、re categories: Color, Texture, Shape, Motion and Localization. The color description tools include five color descriptors to represent different aspects of color features: representative colors (DominantColor), color distribution (ScalableColor), spatial distribution of colors (ColorLayout and Color
23、Structure) and perceptual feeling of illumination color (ColorTemperature). It also contains three supporting tools, ColorSpace and ColorQuantization used in DominantColor and IlluminationInvariantColor to extend four color descriptors, DominantColor, ScalableColor, ColorLayout and ColorStructure, t
24、o support illumination invariant similarity matching. An extension of ScalableColor to a group of frames or pictures (GoFGoPColor) is also included in this group. All the color descriptors can be extracted from arbitrarily shaped regions. The texture description tools facilitate browsing (TextureBro
25、wsing) and similarity retrieval (HomogeneousTexture and EdgeHistogram) using the texture of a still or moving image region. All the texture descriptors can be extracted from arbitrarily shaped regions. The shape description tools include two descriptors that characterize different shape features of
26、a 2D object or region. The RegionShape descriptor captures the distribution of all pixels within a region and the Contour Amendment 3:2010 to CAN/CSA-ISO/IEC 15938-3-04ISO/IEC 15938-3:2002/Amd.3:2009(E) 2 ISO/IEC 2009 All rights reservedShape descriptor characterizes the shape properties of the cont
27、our of an object. The extension of RegionShape is also defined as ShapeVariation to describe temporal variation of shape over video segment. The Shape3D and Perceptual 3D Shape descriptors provide 3-dimensional shape information; the former represents an intrinsic shape characterization of 3D mesh m
28、odels, and the latter represents part-based representation of a 3D object. The motion description tools include four descriptors that characterize various aspects of motion. The CameraMotion descriptor specifies a set of basic camera operations such as, for example, panning and tilting. The motion o
29、f a key point (pixel) from a moving object or region can be characterized by the MotionTrajectory descriptor. The ParametricMotion descriptor characterizes an evolution of an arbitrarily shaped region over time in terms of a 2D geometric transformation. Finally, the MotionActivity descriptor capture
30、s the pace of the motion in the sequence, as perceived by the viewer. All motion descriptors except for CameraMotion can be extracted from arbitrarily shaped regions. The localization description tools can be used to indicate regions of interest in the spatial (RegionLocator) and spatio-temporal (Sp
31、atioTemporalLocator) domains. The FaceRecognition descriptor and the Advanced Face Recognition descriptor are not associated with any particular visual feature and can be used to describe a human face for applications requiring the matching and retrieval of face images. The ImageSignature descriptor
32、 provides a “fingerprint“ of an image that uniquely identify it. 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. The ImageSigna
33、ture has no direct association with specific visual features such as colour, shape or texture.
