چکیده
In this paper we address the problem of detecting shots of subjects that are interviewed in news sequences. This is useful since usually these kinds of scenes contain important and reusable information that can be used for other news programs. In a previous paper, we presented a technique based on a priori knowledge of the editing techniques used in news sequences which allowed a fast search of news stories. In this paper we present a new shot descriptor technique which improves the previous search results by using a simple, yet efficient algorithm, based on the information contained in consecutive frames. Results are provided which prove the validity of the approach.

متن کاملAM-FM IMAGE ANALYSIS TECHNIQUES - Image Analysis and Interpretation, 1996., Proceedings of the IEEE Southwest Symposium on
We present an overview of AM-FM image analysis techniques. Many nonstationary textured images are multi-partite, and may be considered to comprise several locally narrowband components. We introduce a multi-component AM-FM model useful in describing such images, and show that the components may be demodulated on a spatially local basis using multiband filtering followed by a computationally eff...
متن کاملOPTIMALLY WEIGHTED HIGHPASS FILTERS USING MULTISCALE ANALYSIS - Image Analysis and Interpretation, 1996., Proceedings of the IEEE Southwest Symposium on
In this paper, we propose a general framework for studying a class of weighted highpass filters. Our framework, based on a multiscale signal decomposition, allows us to study a wide class of filters and to assess the merits of each. We derige an automatic procedure to optimally tune a filter to the local structure of the image under consideration. The entire algorithm is fully automatic and req...

متن کاملNonparametric motion characterization using causal probabilistic models for video indexing and retrieval
This paper describes an original approach for content-based video indexing and retrieval. We aim at providing a global interpretation of the dynamic content of video shots without any prior motion segmentation and without any use of dense optic flow fields. To this end, we exploit the spatio-temporal distribution, within a shot, of appropriate local motion-related measurements derived from the ...
