Abstract

In this paper, we develop a tracking method for the deformable boundary curves of biological organs using variational registration method. We first define the relative distortion of a pair of curves using curvatures of curves. This minimum distortion aligns corresponding points of a pair of curves. Then, we derive the mean of curves as the curve which minimises the total distortion of a collection of shapes. We compute the intermediate boundary curve of a pair of curves as the mean of these curves.
