There is a need for automatic processing and extracting of meaningful metadata from multimedia information, especially in the audiovisual industry. This higher level information is used in a variety of practices, such as enriching multimedia content with external links, clickable objects and useful related information in general. This paper presents a system for efficient multimedia content analysis...
chapter
A system for efficient multimedia content analysis and automatic annotation is presented in this paper. The system is able to identify objects in videos and annotate them with metadata. It includes three modules: the first provides detection and recognition of faces; the second provides generic object detection, based on a deep convolutional neural network; the third provides automated location estimation...

Local image features are routinely used in state-of-the-art methods to solve many computer vision problems like image retrieval, classification, or 3D registration. As the applications become more complex, the research for better visual features is still active. In this paper we present a feature detector that exploits the inherent geometry of sampled image edges using α-shapes. We propose a novel...

Museums, libraries, national archives and art galleries deal with visual objects that must be made accessible to a wide variety of experts or non-experts like researchers, art lovers or interested people. The ability to identify objects sharing some aspect of visual similarity can be useful when trying to trace historical influences or when looking for further examples of paintings, sculptures or...

Existing methods for the semantic analysis of multimedia, although effective for single-medium scenarios, are inherently flawed in cases where knowledge is spread over different media types. In this work we implement a cross media analysis scheme that takes advantage of both visual and textual information for detecting high-level concepts. The novel aspect of this scheme is the definition and use...
