Executive Summary

Transfer function design is an integrated component in volume visualization and data exploration. The common trial-and-error approach for transfer function searching is a very difficult and time consuming process. A goal-oriented and parameterized transfer function model is, therefore, crucial in guiding the transfer function searching process for better and more meaningful visualization results. This paper presents an image-based transfer function model that integrates 3D image processing tools into the volume visualization pipeline to facilitate the search for an image-based transfer function in volume data visualization and exploration.
