This paper describes the development of a multimedia information system to support the discourse analysis of video recordings of television programs. Although the TV system is one of the most fascinating media phenomena ever created by men, there is still a lack of information systems that allow an effective retrieval of TV information relevant to the(More)
This work addresses the development of a unified approach to content-based indexing and retrieval of digital videos from television archives. The proposed approach has been designed to deal with arbitrary television genres, making it suitable for various applications. To achieve this goal, the main steps of a content-based video retrieval system are(More)
This paper presents a novel multimedia information system, called SAPTE, for supporting the discourse analysis and information retrieval of television programs from their corresponding video recordings. Unlike most common systems, SAPTE uses both content independent and dependent metadata, which are determined by the application of discourse analysis(More)
We present a fast and accurate method for human head detection in range images captured by a stereo camera that is positioned vertically, pointing from the roof to the ground. We show how a static grid of measure points (pylons) can outperform hill climbing techniques and how a fast median filter can be used for effective preprocessing of the range data.(More)
This paper presents a multimodal approach to perform content-based sentiment analysis in TV newscasts videos in order to assist in the automatic estimation of polarity tension of TV news. The proposed approach aims to contribute to the semiodiscoursive study relative to the construction of ethos of those TV shows. In order to achieve this goal, it is(More)
This paper presents the design and development of a new plug-in to the well-known MIPS Assembler and Runtime Simulator (MARS). The MIPS processor is a reduced instruction set computer (RISC), while the MARS simulator is a lightweight interactive development environment for programming in MIPS assembly language, intended for educational-level use. The(More)
