This paper presents an architecture and a corresponding prototype implementation of a distributed system for visualization and sonification of scientific data. The distribution is accomplished by the addition of visualization and sonification servers, accessible over the Internet, and implemented using an XML-based SOAP (Simple Object Access Protocol) protocol. The system is an evolution of a previously-developed prototype, with improvement in the visualization and in the distribution aspects of the architecture. The former distribution scheme employed CORBA (Common Object Request Broker). A discussion on the use of both distribution tools is given in the light of visualization tasks.","PeriodicalId":286814,"journal":{"name":"Proceedings.

The goal of this paper is to present a texture classification system for remote sensing images aimed at the administration of large collections of those images. The proposed classifier is a hybrid system composed by an unsupervised neural network and a supervised one. Starting from a small portion of the image (pattern) the system should recognize the most similar class to a pattern in a database as well as to identify images that contain similar patterns. The texture feature vectors used to characterize the patterns are obtained from the images processed by a bank of Gabor filters. Experimental results using textures of the Brodatz album, multi-spectral and radar images are presented.","PeriodicalId":286814,"journal":{"name":"Proceedings.

The generated textures are perceived as very similar to the given sample. One main drawback of these techniques, however, is that the synthesized result cannot be locally controlled, that is, we are able to synthesize a larger version of the sample but without much variation. We present in this paper a technique which improves on current fast texture synthesis techniques by allowing local control over the result. By local control we mean a final texture that is still perceived as a whole but presents variations in size of the basic elements. Our solution generates the final texture from a small collection of the same sample at different resolutions, adequately interpolated. We illustrate our results with some examples, including natural textures such as animal coat patterns, which exhibit local variations that can be adequately captured by our algorithm.","PeriodicalId":286814,"journal":{"name":"Proceedings.

However, in order to do this, it is necessary to use a reliable and efficient process able to identify and to extract the information, which can then be submitted to a further recognition phase. We present a process for identifying and distinguishing between handwritten information and machine printed text based on a set of local features. This process is based on the characterization of textual elements via properties derived from their content and their shape. The main advantage of this process compared with other similar approaches is that no a priori information of the treated document is used, thus making it more generic and effective.","PeriodicalId":286814,"journal":{"name":"Proceedings.

While traditional fractal dimensions provide interesting possibilities for quantifying pattern complexity, as defined by the intensity in which the pattern interacts with its surrounding space, those approaches fail to take into account the important fact that natural objects are not perfectly self-similar. By expressing the fractal behavior explicitly in terms of the spatial scale, the MFD provides a more comprehensive and objective characterization of the complexity of natural data such as gene expression profiles. After presenting the MFD concept as well as a technique for its numerical estimation, the potential of this measure for objectively quantifying gene expression is discussed, and a complete example is provided regarding the three-dimensional expression of the myogenic marker gene Myf5 along successive somites in a mouse embryo. In this specific case, the adopted technique proved itself a useful means for identifying spatial variations of gene expression intensity.","PeriodicalId":286814,"journal":{"name":"Proceedings.
