DISEÑO E IMPLEMENTACIÓN DE UNA BASE DE DATOS DE IMÁGENES DE RANGO CON DECIMACIÓN PARA LA VISUALIZACIÓN EN WEB.

Databases are tools to store and manage information, the better they are distributed, the easier and more efficient will its access be. At present, thanks to technological development of fields such as computer science and electronics, most of them have an electronic format, since they offer a wide rank of solutions to the store data problem. In this paper, we present the design and development of a database for range images, based on the relational model and a design methodology consisting of three steps: conceptual design, logical design, and physical design. The data base has a WEB access. A multi-resolution algorithm was developed to improve the time cost in visualization and renderization, by using decimation parameters based on the curvature. A WEB interface was developed in order to provide an easy access, consequently, it is possible to enter, update, and eliminate models on a reliable and simple way. At present, the database counts on 40 models divided in 3 categories: Faces (22), Museum (4) and objects of free form (14). The use of the multi-resolution algorithm allows saving up to 96% of computational cost. [ABSTRACT FROM AUTHOR]
