Abstract:
1. A method for population-driven identification of body landmarks comprising steps, performed in an information processing device, of: providing a set of landmark information for a landmarked population, wherein three-dimensional landmarks are identified for each individual in the landmarked population, such that three-dimensional geometry of the each individual is obtained, wherein the landmark information of the each individual comprises a plurality of three-dimensional part meshes; scanning a plurality of three-dimensional scans of a subject body, a human body; generating a preliminary parameterized body from the plurality of three-dimensional scans; and part-wise matching to find a best-matched landmarked part-mesh in the landmarked population to a given body part of the subject body and apply a body landmark (BL) thereof to the given body part, wherein the step of providing comprises steps of: parameterizing each individual of the landmarked population through mesh transformation for establishing correspondence between body points of two arbitrary individuals in the landmarked population; and performing topological body segmentation on each individual of the landmarked population in order to obtain the three-dimensional part meshes, wherein the step of part-wise matching comprises steps of: aligning/scaling the landmarked part-mesh around the subject body; and selecting a part-mesh with a lowest registration error, wherein the registration error is given as where T represents a transformation applied to a topological part-mesh P
