Predicting precision grip grasp locations on three-dimensional objects
Fig 14
All panels show model performance (in terms of grasp similarity to human data from Experiment 3) as a function of different perturbations. Grasp similarity for the original model implementation is shown in green. Red and black dashed lines are respectively human and chance levels of grasp similarity, bounded by 95% bootstrapped confidence intervals. (a) Model grasp similarity with input meshes subsampled by varying degrees. (b) Model grasp similarity for model implementations employing increasing aperture thresholds. (c, d) Model grasp similarity for models implemented with deviated natural grasp axis along the transverse (c) and sagittal (s) planes.
