Title: Inverse Anatomical Modeling and Simulation of Virtual Humans Author: RNDr. Petr Kadleček Department: Department of Software and Computer Science Education Supervisor: Mgr. Ladislav Kavan, Ph.D., Department of Software and Computer Science Education Abstract: In this dissertation, we focus on a mechanical aspect of a human body and face modeling. We leverage existing physics-based models of elasticity and use them as building blocks to create an animatable virtual human. We model different types of hard and soft tissues to enable our model to contract muscles, interact with an environment or realistically deform when subjected to external forces. In the first part of the work, we present a method to create personalized anatom- ical models of human body ready for physics-based animation, using only a set of 3D surface scans. We start by building a template anatomical model of an average male which supports deformations due to both 1) subject-specific vari- ations: shapes and sizes of bones, muscles, and adipose tissues and 2) skeletal poses. Next, we capture a set of 3D scans of an actor in various poses. Our key contribution is formulating and solving a large-scale optimization problem where we compute both subject-specific and pose-dependent parameters such that our resulting anatomical model...
