The rapidity with which digitat information, particularly video, is being generated, has necessitated the development of tools for efficient search of these media. Content based visual queries have been primarily focussed on still image retrieval. In this papel; we propose a novel, real-time, interactive system on the Web, based on the visual paradigm, with(More)

The rapid growth of visual data over the last few years has lead to many schemes for retrieving such data. With content-based systems today, there exists a significant gap between the user's information needs and what the systems can deliver. We propose to bridge this gap, by introducing the novel idea of Semantic Visual Templates (SVT). Each template(More)
In this paper, we propose an efficient wavelet-based approach to achieve flexible and robust motion trajectory matching of video objects. By using the wavelet transform, our algorithm decomposes the raw object trajectory into components at different scales. We use the coarsest scale components to approximate the global motion information and the finer scale(More)
Images and videos can be indexed by multiple features at different levels, such as color, texture, motion, and text annotation. Organizing this information into a system so that users can query effectively is a challenging and important problem. In this paper, we present VISMap, a visual information seeking system that extends the traditional query(More)
Phylogenetic tools and ‘tree-thinking’ approaches increasingly permeate all biological research. At the same time, phylogenetic data sets are expanding at breakneck pace, facilitated by increasingly economical sequencing technologies. Therefore, there is an urgent need for accessible, modular, and sharable tools for phylogenetic analysis. We developed a(More)
Belief networks have become an increasingly popular mechanism for dealing with uncertainty in systems. Unfortunately, it is known that nding the probability values of belief network nodes given a set of evidence is not tractable in general. Many diierent simulation algorithms for approximating solutions to this problem have been proposed and implemented. In(More)

We have implemented a number of real-time signal processing kernels and applications within the Ptolemy simulation and code generation environment. Our goal is to make it easy to generate real-time programs with configurable interactive user interfaces. As part of this project, we have developed and benchmarked some key signal processing kernels for the new(More)
