In the context of medical volume visualization, it is useful to study how effectively the visualization depicts anatomical structures and how well features of anatomical structures can be discerned in order to make decisions. So it is important to know what factors affect the understanding of rendered images and further to design more effective rendering algorithms under considering these factors. However, they are not fully evaluated. These are important for users to get better understanding of a 3D data set, and to help to develop effective visualization methods. Because visualization renditions are perceived through human visual perception, visual perception has important effects on mental models. This paper aims to analyze the roles of perception for volume visualization and use the perceptual analysis results to design volume visualization methods.
In this paper we describe an experiment to obtain information about the perceptual potential of the human visual system regarding shadow perception. Shadows play an important part for communicating spatial structures ...

In compositing applications, objects depicted in images frequently have to be separated from their background, so that they can be placed in a new environment. Alpha mattes are important tools aiding the selection of ...

In this work we propose a framework for image processing in a visual response space, in which contrast values directly correlate with their visibility in an image. Our framework involves a transformation of an image f...

Layered motion fields arise in natural vision in many situations, including self-motion in a cluttered scene, motion of a fluid, and transparency. Layered motion fields have the property that there are multiple veloci...

In this paper, we take a new look at the problem of texturing surfaces so that they can be displayed layered over each other but remain clearly visible. Finding optimal textures that solve this problem is complex beca...

Controlling computers by eyes can provide a fast and efficient alternative to the computer mouse. However, in gaze controlled systems object selection is still suboptimal: Dwell times on a certain object typically use...

How different are two images when viewed by a human observer? Such knowledge is needed in many situations including when one has to judge the degree to which a graphics representation may be similar to a high-quality ...
