This paper presents a protein visualization system called BioBrowser, which provides high quality images at interactive frame rates for molecules of extreme size and complexity. This is achieved by a shift in the tessellation approach: triangle meshes are not produced a priori on a ’just-in-case’ basis. Instead, tessellation happens ’justin-time’ given a certain camera position, image size and ...

We present a new fuzzy logic programming Language, called LIKELOG, to be used for approximated reat;oning and for fuzzy deductive database applications. The core component of the system is the algori thm of unification, which expands the Martelli-Montanari unification algorithm introducing two similarity relations. The resolution mechanism is a straightforward application of this kind of expand...

Although signi cant progress has been made in developing multidatabase systems that integrate component databases containing crisp data, little has been reported on integrating fuzzy databases in such systems. In this paper, we investigate the problem of integrating fuzzy relational databases in a multidatabase system. We identify new types of con icts that may occur in schemas and data due to ...

Common users have changed from mere consumers to active producers of multimedia data content. Video editing plays an important role in this scenario, calling for simple segmentation tools that can handle fast-moving and deformable video objects with possible occlusions, color similarities with the background, among other challenges. We present an interactive video segmentation method, named FOM...

OBJECTIVES Aiming to improve the anatomical resolution of electrical impedance tomography images, we developed a fuzzy model based on electrical impedance tomography's high temporal resolution and on the functional pulmonary signals of perfusion and ventilation. INTRODUCTION Electrical impedance tomography images carry information about both ventilation and perfusion. However, these images ar...
