This paper proposes a novel binary image descriptor, namely the Adaptive Hierarchical Density Histogram, that can be utilized for complex binary image retrieval. This novel descriptor exploits the distribution of the image points on a two-dimensional area. To reflect effectively this distribution, we propose an adaptive pyramidal decomposition of the image into non-overlapping rectangular regions...
This paper presents the video retrieval engine VERGE, which combines indexing, analysis and retrieval techniques in various modalities (i.e. textual, visual and concept search). The functionalities of the search engine are demonstrated through the supported user interaction modes.
This paper describes a video retrieval search engine that exploits both video analysis and user implicit feedback. Video analysis (i.e. automatic speech recognition, shot segmentation and keyframe processing) is performed by employing state of the art techniques, while for implicit feedback analysis we propose a novel methodology, which takes into account the patterns of user-interaction with the...
This paper proposes an open flexible learning oriented technological framework for interactive digital TV (iDTV). The framework is designed to satisfy the pedagogical requirements and deal with the iDTV capabilities and constraints. The framework includes two main products: the authoring tool, where the course is prepared and the course multimedia player, which is capable of presenting the course...
Nowadays, an increasingly growing demand for the creation of digital multimedia libraries is arising, as huge amounts of digital visual content are becoming available. The content that resides in these libraries should be easily retrievable and classified in order to be fully accessible. This paper introduces a hybrid multimedia retrieval model accompanied by the presentation of a search engine that...
