Abstract:

Due to the volume preserving constraint of human muscle in the deformation process, and the lack of three-dimensional multi-angle representation of muscle motion, a parametric modeling and deformation method of human muscle is proposed. Based on MRI (magnetic resonance imaging) data, the external contour line is extracted from the slice image generated by MRI data to construct a three-dimensional muscle model; muscle features are defined hierarchically, and the mapping relationship between semantic parameters is established to realize the volume preserving deformation of muscle; by establishing a vector-valued dynamic fourth-order differential equation, the feature curve dynamically simulates the process of muscle deformation, and establishes the corresponding relationship between skeletal motion and muscle deformation. The effectiveness of this method is verified by experiments with biceps brachii as an example.

Key words: muscle modeling, characteristic curve, parameterization, volume preserving, dynamic deformation
