Abstract
A tracking system converts images to a set of points in 3D space. The images are of a wearable item that includes markers, and the set of points include representations of the markers. A view is selected from a plurality of views using the set of points, and the selected view includes one or more representations of the representations. A depth map is generated based on the selected view and the set of points, and the depth map includes the one or more representations. A neural network maps labels to the one or more representations in the depth map using a model of a portion of a body that wears the wearable item. A joint parameter is determined using the mapped labels. The model is updated with the joint parameter, and content provided to a user of the wearable item is based in part on the updated model.
