3D SHAPE ASYMMETRY ANALYSIS USING CORRESPONDENCE BETWEEN PARTIAL GEODESIC CURVES

Abstract: 

Analyzing the asymmetry of anatomical shapes is one of the cornerstones of efficient computerized diagnosis. In the application of scoliotic trunk analysis, one major challenge is the high variability and complexity of deformations due to the pathology itself, and to changes of body poses, for instance, torsos acquired in lateral bending poses for surgical planning. In this paper, we present a novel and fully automatic approach to analyzing the asymmetry of deformable trunk shapes. Our method detects the symmetry plane/axis of the shape and a set of reflective geodesic curves; the method then uses parts of these geodesics to compute point correspondence between any reflective pair. We present a preliminary study on scoliotic torsos in neutral standing and lateral bending poses. Our results show that matching parts of reflective curves is robust against non-isometric deformations. The proposed method can extend to other applications, such as maxillofacial surgery planning
