Quantifying the objective quality of voxel based data visualizations produced by a ray caster: a proposal
Beatriz Sousa Santos, J. Nunes, C. Coimbra, Carlos Manuel dos Santos Ferreira, Ana Maria Tomé, Nuno Lau · 2002
A set of parameters to assess the objective quality of visualizations of a voxel-based data set, produced using a ray caster, is proposed as a first step toward the evaluation of the overall quality of these visualizations. Results obtained using synthetic data and a simple implementation of a ray caster are presented. The final goal of this evaluation is the computation of "confidence indices" that could offer the user a "guided visualization", i.e. allow him/her to decide what are the "best" visualizations of a data set.
