They can realize a bridge to a large-scale archive for their solutions. Main benefits of the product in respect to products that are on the market at present are: - Easy to use interface - Proven and reliable interface standard http - Proven security functions available (https, SSL etc.) - Widely configurable e.g. port numbering, URL etc. - The assets are protected against writing and changing - Interface can adapted very easily e.g. to switch off certain services or hide certain data - Output of the interface can be adapted easily via style sheets.
The result is an advanced visualization tool for information activities like exploring information spaces and judging relevance of information items in these spaces. It supports interactive clustering of the query result by manipulation of term positions. Furthermore, the user is provided with an interactive relevance feedback mechanism. He can express a higher/lower interest in a specific query and the related image cluster by in/decreasing the query symbol's attraction towards its images. The relevance of the images (Key-frames) is coded to its position within the circle. The closer an image is positioned to the boarder of the circle, the more relevant it is in the whole query context; the closer it is positioned to a terms' position, the more relevant it is with regard to this term. Possible end-users for the product are any users who want to visually judge and manipulate their search results, e.g. broadcasting archives, national and international archives, news agencies, advertising companies and marketing and PR departments of big enterprises. Further users can be national and international security and monitoring organization that deal with images as representatives of audiovisual material and preservation e.g. of crime, history or violation of human rights. Main benefits of the product in respect to products that are on the market at present are: - Exploring information spaces and judging relevance of information items in these spaces - Interactive clustering of results sets - Interactive relevance feedback mechanism The technology could be used in systems that offer search by textual as well as visual metadata.
The result is a web based user interface to be used with a standard web browser (MS Internet Explorer). The user interface is designed to administer the above mentioned COMPASS search engine (product No. 5), but can re-used and adapted to other search engines or related software products (e.g. databases). Possible end-users for the product are the same as for the COMPASS product i.e. broadcasting archives, national and international audiovisual archives, news agencies, advertising companies and marketing and PR departments of big enterprises. Other application of image searching and therefore for this interface can be medical imaging, security applications or life sciences. Other end users could be consulting and system integration companies that offer integrated archiving or retrieval solutions for customers. Main benefits of the product in respect to products that are on the market at present are: - Web based interface relying on common standards - Easy to adapt to other script-based administration interfaces - Both for LINUX and Windows systems. The technology is superior to systems that offer separate searches. The new product can combine the retrieval and the results of several search engines.
The result is a flexible feature-based retrieval engine. The engine could be trained based on the user requirements and which features are interesting. Prerequisites are: good image quality and an expert classification of the training set. The retrieval engine is using the content-based retrieval technique, an up-to-date and promising one. The engine is generic and could be used in any image retrieval system. Possible end-users for the product are broadcasting archives, national and international archives, news agencies, advertising companies and marketing and PR departments of big enterprises. Further users can be national and international security and monitoring organization that deal with images as representatives of audiovisual material and preservation e.g. of crime, history or violation of human rights. Main benefits of the product in respect to products that are on the market at present are: - Advanced image analysis and indexing - Content-based video/image retrieval - Flexible and customisable retrieval engine. The technology is superior to systems that offer only search by textual metadata. The new product exploits the power of content-based search methods.
COMPASS is a server application providing image indexing and retrieval services based on automatic description of image visual features such as color, texture, and luminance. The client application can then feed to the server a query formulated by sample images, representing both wanted and unwanted images, and obtain from the server the most similar images stored in the database. One of the most salient features of the system is its efficiency: a new database with one million images can be created within a couple of hours and the time needed to search for a single image in such a database is just a few tenth of a second. Major applications are in interfacing large visual databases such as those of major television broadcasters or news agencies. The system has been extensively tested and its straightforward interface, based on HTTP protocol eases integration with other legacy applications. An extensive set of image descriptors, taking into account region shapes and layout is available.
The Advanced Video Analysis and Indexing (AVA/I) Engine is a suite of programs able to automatically segment an MPEG stream into shots, provide basic information on audio content, extract key frames using several strategies and generate variable length summaries for web publishing. The most salient feature of the AVA/I Engine is its support for flexible key framing strategies that can rely on information automatically extracted from the digital video streams, such as picture activity, picture quality, audio volume etc. The different fields can be combined into a measure of saliency for each frame, and key frames are extracted based this figure of merit. Major applications are in providing better Web visibility to large visual archives such as those of major television broadcasters or news agencies. Additional applications involve selective processing of video streams for selected object detection.
The result is a web based user interface to be used with a standard web browser (MS Internet Explorer). The product is not a stand-alone application but a user interface that can integrate several textual and content-based search engines and multimedia (especially) video archives. Possible end-users for the product are broadcasting archives, national and international audiovisual archives, news agencies, advertising companies and marketing and PR departments of big enterprises. The product is to integrate several applications that are in use within one common web based interface. Other end users could be consulting and system integration companies that offer integrated archiving or retrieval solutions for customers. Main benefits of the product in respect to products that are on the market at present are: - Web based interface relying on common standards such as http, https, SOAP, XML, XSL and XSLT - Textual, conceptual as well as image similarity search within one interface - Exchange of results between the search processes and interfaces - Advanced visualization technology to cope with large result sets.
