Learning the link between surface and anatomic models of the human body

Internship M1/M2: MORPHEO – ANATOSCOPE
Context
This is a joint project between the MORPHEO INRIA  team and the company ANATOSCOPE which specialises in human anatomy modeling. The main goal of this project is to link two different types of human body representations. On one hand,  external representations with visual human body models [1,2,3] as built from visual observations, and on the other hand intrinsic representations with anatomic models [4,6] as built using MRI or CT scans. The interest is to be able to infer one representation from the other, for instance to infer the anatomy inside a body given its surface observation.
Objective
The objective of this internship is to establish the link between the representations of the surface models [1,2] and the anatomic models [4]. As a starting point, the registrations of surface and anatomic models will be provided [5]. The candidate will leverage machine learning techniques, in order to characterize the relationships between i) the shape space parametrization of SMPL and the anatomic parameters, as well as ii) a free form human shape in SMPL topology and the anatomic parameters. The solutions should provide a fast, accurate and efficient method relating both models. If time allows, the relations between the pose dependent deformations and the anatomic model parameters will also be studied.

Supervision
The project will be supervised by Sergi Pujades (MORPHEO), Edmond Boyer (MORPHEO) and François Faure (ANATOSCOPE).
