This paper addresses the problem of probabilistically modeling 3D human motion for synthesis and tracking. Given the high dimensional nature of human motion, learning an explicit probabilistic model from available training data is currently impractical. Instead we exploit methods from texture synthesis that treat images as representing an implicit empirical distribution. These methods replace t...

The tidal areas of the oceans are important transition zones between terrestrial and marine ecosystems. In contrast to the non-marine surface of the earth, access to the tidal lands such as the Wadden Sea along the North Sea coast is often difficult. For this reason, remote sensing offers important monitoring tools. In this study, a new change detection approach is presented, adapted to the Wad...

Feature-based similarity retrieval has become an iniportant research issue in multimedia database systems. The features of multimedia data are useful for discriminating between multimedia objects (e.g., documents, images, video, music score, etc.). For example, images are represented by their color histograms, texture vectors, and shape descriptors. A feature vector is a vector that represents ...

These effects on tree growth, which may persist for several decades (Hatchell et al. 1970, Butt 1987, Miller et al. 1996), may lead to shortand long-term reductions in tree growth and forest productivity. The level of soil disturbance will vary with soil texture, forest floor thickness, and soil water content at time of harvest (Miller and Sirois 1986, Corns 1988). In addition, machine type, si...

This paper describes a new method for analysis/synthesis of textures using a non-parametric multi-resolution approach able to reproduce efficiently the generative stochastic process of a wide class of real texture images. This is realized through a new data structure the Antipole Tree and a suitable research strategy able to outperform both the classical linear full-search heuristic and the TSV...

T he world that you know and experience with your senses everyday is the natural world. You see it when you see a beautiful sunrise in the early morning. You hear it when you sit on a beach and listen to the waves crashing on the rocks. You feel it when you climb a tree and feel the texture of the branches and the bark. You smell it when you pick strawberries in a strawberry patch. You taste it...

We consider the coding of featured contours, i.e. texture, object or motion boundaries in images. The MPEG-4 and MPEG-7 video coding standards provide for a content-based representation of video information, so efficient coding of boundaries can play an important role. We propose a new coding scheme that uses an asymmetric binary tree. We show that the new scheme outperforms conventional quadtr...

-A new approach to the problem of image segmentation is presented. By combining a nonparametric classifier, based on a clustering algorithm, with a quad-tree representation of the image, the scheme is both simple to implement and performs well, giving satisfactory results at signal-to-noise ratios well below 1. The results of an analysis of the algorithm are borne out by a comprehensive set of ...

We use a conventional matching criterion, the sums of squares of differences, SSD, which is statistically meaningful when ergodicity of its matching regions is assumed. Here, simple statistical similarity measures are applied to the scale tree to simplify it into a set of relatively homogeneous regions. This simplified scale tree is then used to generate matching regions which frequently satisf...
