Perception-based quality metrics for volume rendering
First Claim
1. A system for a perception-based visual quality metric in volume rendering, the system comprising:
- a memory operable to store a dataset representing a three-dimensional volume; and
a processor operable to volume render, as a function of the first setting of the at least one rendering parameter, a two-dimensional representation from the dataset, the two-dimensional representation representing the volume, the first setting being a function of the perception-based visual quality metric;
a display operable to display the two-dimensional representation of the volume, a visual aspect of the two-dimensional representation being more visually perceptible for the first setting than another two-dimensional representation of the volume rendered as a function of a second setting of the at least one rendering parameter.

Abstract
Perception-based visual quality metrics are used in volume rendering. A perception-based visual quality metric is measured from one or more three-dimensional representations. For example, people tend to notice edges, so a numeric value representing the noticeable edges is calculated. The perception-based metric is used for developing volume renderers, calibrating across different renderers, calibrating across different rendering platforms, determining rendering parameter values as a function of rendering speed, selecting rendering parameter values for a given situation, providing a range of rendering options associated with gradual perception changes, and/or combinations thereof. The perception-based visual quality metric provides a quantifiable representation of importance to the user for a given application, assisting optimization of volume rendering.
