Multimodal Visual Learning for Pressure Ulcer Prevention�Anujraaj Goyal, Abhishek Tandon, Zackory Erickson

Objective�Inform where to provide care to prevent pressure ulcers�$ 30 billion/year cost of managing pressure ulcers. Preventable by repositioning

Approach�Use pressure image and depth image as input to predict pressure on human mesh

Method 1

Results

Future Work�Simulate ground truth data for pressure applied on human bodies in rest�Train models with pressure and depth image reconstruction losses

Metric � v2vP - vertex to vertex pressure error (kPa2)
