Abstract
An illustrative 3D modeling system generates a hair orientation image based on a 2D image depicting a human subject having hair. The hair orientation image includes semantic segmentation data indicating whether image elements of the hair orientation image depict the hair of the human subject or content other than the hair. The hair orientation image further includes hair flow data indicating a flow direction of the hair depicted by various image elements. Based on the hair orientation image, the 3D modeling system generates a 3D model of the hair of the human subject. The 3D modeling system then integrates the 3D model of the hair of the human subject with a 3D model of a body of the human subject. Corresponding methods and systems are also disclosed.
