Anatomical Landmarks Localization for 3D Foot Point Clouds
This addresses the problem of automating landmark localization for health research, specifically in foot anatomy, but appears incremental as it builds on existing deformation approaches.
The paper tackles automated localization of 3D anatomical landmarks in foot point clouds by introducing a deformation method that non-rigidly aligns a source model to a target, achieving better performance than state-of-the-art techniques in most cases.
3D anatomical landmarks play an important role in health research. Their automated prediction/localization thus becomes a vital task. In this paper, we introduce a deformation method for 3D anatomical landmarks prediction. It utilizes a source model with anatomical landmarks which are annotated by clinicians, and deforms this model non-rigidly to match the target model. Two constraints are introduced in the optimization, which are responsible for alignment and smoothness, respectively. Experiments are performed on our dataset and the results demonstrate the robustness of our method, and show that it yields better performance than the state-of-the-art techniques in most cases.
