Leveraging Anthropometric Measurements to Improve Human Mesh Estimation and Ensure Consistent Body Shapes

Katja Ludwig, Julian Lorenz, Daniel Kienzle +2

The basic body shape (i.e., the body shape in T-pose) of a person does not change within a single video. However, most SOTA human mesh estimation (HME) models output a slightly dif…

A Fair Ranking and New Model for Panoptic Scene Graph Generation

Julian Lorenz, Alexander Pest, Daniel Kienzle +2

In panoptic scene graph generation (PSGG), models retrieve interactions between objects in an image which are grounded by panoptic segmentation masks. Previous evaluations on panop…
