Mpeg-7 xm reference software

The GenericDS class does not implement the data structure in a dedicated way, but it is an interface to the XML parser library which controls the memory for the tree structure of the instantiated D or DS. Coding Schemes are specific coding and decoding methods defined for individual Descriptors and Description Schemes. If an individual coding schemes is available, it represents a normative part of the standard.

Coding schemes are available for the visual descriptors to encode or to decode a description into its binary representation. Matching tools are specific search, or matching methods defined for each Descriptor and Description Scheme. Matching tools are not normative in the implementation but they are depending on the specified application of the description. The matching tools can be used in two different ways: to compute distances between descriptions for the purpose of indexing, and to search in the descriptions based on a query with the purpose of transcoding.

These procedural blocks are part of the functionality of specific application modules. They are not represented by dedicated module classes in the XM software. They need to be integrated in the XM when implementing a specific transcoding application. Applications are expressed by the classes combining the modules of a Descriptor or a Descriptions Scheme including modules of their sub-Ds and -DSs.

The resulting class implements one of the three key applications shown in Figure 1, 2, 3. The components of the reference software, which are corresponding to a descriptor or description scheme, are implemented using a specific interface mechanism.

Besides using private and public functions all classes have an individual interface class, which interfaces the public methods of the class itself. This is done to increase the reusability of the code. For example, by making all destructors private it is possible to force a dedicated way of instantiating objects of this class.

Thus, in case of code reuse, the way of destructing the object is fixed. For the reuse of classes two mechanisms are implemented. In such case a reference counting mechanism is implemented. This is not required for the coding scheme classes, the extraction classes, and the search classes. Therefore, these classes do not use a reference counting mechanism. These classes use the reference counting mechanism of the descriptor class to manage the memory of the description data.

This software has been derived from the verification models used in the process of developing the International Standard. This International Standard, also known as "Multimedia Content Description Interface," provides a standardized set of technologies for describing multimedia content. It addresses a broad spectrum of multimedia applications and requirements by providing a metadata system for describing the features of multimedia content. Part 6 — Reference software: provides a software implementation of the International Standard.

This software has been derived from the verification models used in the process of developing the standard. Where multimedia content extraction or multimedia content description software is provided, attention is called to the fact that these software modules are provided for the purpose of creating bit streams of descriptors and description schemes with normative syntax.

The performance of these software tools should not be taken as indicative of that which can be obtained from implementations where quality and computational optimization are given priority. The techniques used for extracting descriptors or deriving description schemes are not specified by this document.

This information can be found in the corresponding sections of Part The reference software operates on and generates conformant bitstreams.

The function of this software module is explained in Clause 7 of this document. This software creates standard visual descriptions from associated visual media content as explained in Clause 8 of this document. Anyone who had experience with this Mpeg-7 Xm Software before? It was really hard to find, but it worked. After these changes, It was successfully compiled.

Also, it may work on many other versions as well. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams? Collectives on Stack Overflow. Learn more. Asked 10 years, 10 months ago. Active 10 years, 10 months ago.
