F. B. Sachse, M. Wolf, C. D. Werner, and K. Meyer-Waarden. Extension of anatomical models of the human body: three dimensional interpolation of muscle fiber orientation based on restrictions. In Journal of Computing and Information Technology, vol. 6(1) , pp. 95-101, 1998
This paper is the extension of a detailed anatomical model (Sachse et al., 1996a) (Sachse et al., 1996b) with the three-dimensional orientation of skeletal muscle fibres (Figure 1). The orientation is interpolated basing on two sets with restrictions of different types. The first set consists of points for which the orientation is known. The second set consists of points with an assigned normal of orientation. These sets are created by detection with manual or automatic methods using techniques of digital image processing. The interpolation works iteratively employing the averaging orientations in the 6-neighbourhood. The average of neighbouring orientations is calculated by determination of their principal axis.
