 Dataset of tactile images collected over grasping common objects labelled with the objects' Young's Moduli. All images are collected using GelSight Wedges, both with and without displacement markers. Associated code is available on [GitHub](https://github.com/GelSight-lab/EstimateModulus/tree/main).
 
+Pre-print is available on [arXiv](https://arxiv.org/abs/2406.15304).
