Structure-Aware Lighting Design for Volume Visualization Perceptual structural differences between images rendered with and without external lighting in direct volume rendering without external lighting with external lighting SSIM HWSD Homogeneity-Weighted Structural Dissimilarity Metric (HWSD)
Structure-Aware Lighting Design for Volume Visualization Lighting characteristics based on SSIM and HWSD Lighting goodness, lighting similarity, lighting stability Structure-aware automatic lighting design approach light position sphere one optimal light two optimal lights optimal light parameters
