java is an object-oriented program that has abundant open-source libraries for application development and 3d model rendering. spatial database is the database that can efficiently store and manage geographic information data though various spatial data management techniques. this paper explores the rationale of coupling java with spatial database to develop an effective platform for future bui...

A semantic database has been extended with visual information to enable video annotation. This paper describes a lexical database, WordNet. We show its limitations with respect to describing visual characteristics, and describe an extension to WordNet that contains specific visual information. Having such a semantic database makes video annotation possible for Broadcast News: a domain that can ...

In this paper we present a simple novel approach to tackle the challenges of scaling and rotation of face images in face recognition. The proposed approach registers the training and testing visual face images by log-polar transformation, which is capable to handle complicacies introduced by scaling and rotation. Log-polar images are projected into eigenspace and finally classified using an imp...

For past several decades, visual speech signal processing has been an attractive research topic for overcoming certain audio-only recognition problems. In recent years, there have been many automatic speech-reading systems proposed that combine audio and visual speech features. For all such systems, the objective of these audio-visual speech recognizers is to improve recognition accuracy, parti...

Visual impression may di er with each person. User-friendly interfaces for image database systems require special retrieval methods which can adapt to the visual impression of each user. This paper describes algorithms for learning personal visual impression on visual objects. The algorithms are based on multivariate data analysis methods. These algorithms provide a model on visual perception p...

In this paper we describe the design, recording, and content of a large audio-visual speech database intended for training and testing of audio-visual continuous speech recognition systems. The UWB05-HSCAVC database contains high resolution video and quality audio data suitable for experiments on audio-visual speech recognition. The corpus consists of nearly 40 hours of audiovisual records of 1...
