This dataset contains paired images of photorealistic cuneiform tablet renders and their corresponding MSII (Multi Scale Integral Invariant) curvature visualizations. Both are rendered in Blender at 4096px max axis.

Background & Motivation

Cuneiform tablets contain impressions made in clay thousands of years ago. These subtle surface variations are often difficult to see in regular photographs, especially under poor lighting conditions. MSII (Multi Scale Integral Invariant) filtering is a curvature visualization technique that highlights these impressions by computing surface curvature at multiple scales, making cuneiform characters clearly visible regardless of lighting.

However, getting the MSII visualization of a tablet requires a 3D scan and lots of computation. To reduce this barrier and increase the availability of easy-to-read images, I'd like to train a diffusion model to predict the MSII visualization directly from photographs.

To do that, I've created this high quality dataset intended for training.

Source Data

This project uses the HeiCuBeDa (Heidelberg Cuneiform Benchmark Dataset), a professional research dataset of 1,747 high-resolution 3D scans.

Image Diversity

To get the most out of the 1.7K tablet scans from HeiCuBeDa, we generate several varied images for each tablet.

Each variant gets an independent random selection of:

What VariesDescriptionRange
FacesWhich of the six faces are shown in the imageVariant 1 always shows 6 faces. Variants 2+ have a 20% chance of all 6, otherwise uses per-face probs (front 100%, back 75%, top/bottom 45%, left/right 30%)
RotationRotation of the tablet±5° Euler XYZ
Focal lengthThe focal length of the camera80–150 mm
LightingThe position, color, and intensity of the lights in the photo±30% Energy. ±2% Warmth. Random offset along the perpendicular plane
BackgroundThe image behind the tablet in the photo70% use no background. 30% select from fabric/grunge/stone (weighted). Rotation/scale/offset are randomized. Perlin noise is used to vary brightness throughout.

Known Limitations

  • —Renders may not capture all real-world photo degradation
  • —MSII visualization quality depends on PLY mesh resolution and artifacting
  • —Generalization to real photos vs. renders needs validation
