Methods are presented for the visualization of fuzzy data based on the sensitivity of the human visual system to motion and dynamic changes, and the ease of which electronic display devices can change their display. The methods include taking an otherwise static image and displaying in an animation loop either its segmented components or a series of blurred versions of the whole image. This approach was applied to sea-surface temperature data and was found to be effective in showing fuzzy details embedded in the data, and in drawing the viewer's attention. This approach and these methods could play a significant role in the display of browse products for massive data and information systems.>

An algorithm based on mathematical morphology, image processing, and volume rendering has been developed to enhance the visual perception of definite and abstract structures embedded in multidimensional data undergoing visualization. This erosion procedure enhances the depth and shape perception of structures present in the data beyond the perception facilitated by shading and contrasting colors alone. The utility of this algorithm is demonstrated for medical imaging (positron emission tomography) and climate (sea surface temperature) data. The resulting information is displayed in stereo.>

The author applied image processing and volume rendering algorithms together with considerations on the physiology of the human visual system to improve the quality of perception of the information contained in positron emission tomography (PET) brain images, and to highlight the existing anatomical information. The psychophysical considerations for selecting color and brightness level are used to visualize functional and anatomical structures in three dimensions. One is able to perceive in the images the levels of rates of glucose metabolism of regions in the brain and their relative locations. In addition, some of the anatomic structures, such as the interhemispheric fissure, the caudate nucleus, and the thalamus, are apparent.>
