In order to design industrial products fitting well to the human body, it is necessary to make full use of information of human anatomical landmarks. These landmarks however cannot be extracted automatically from point cloud data of human body surface obtained by a 3D scanner. In our previous report, we proposed the method of extracting the landmarks automatically by deforming the template of p...

For many fundamental problems and applications in biomechanics, biology, and robotics, an in-depth understanding of animal locomotion is essential. To analyze the locomotion of animals, high-speed X-ray videos are recorded, in which anatomical landmarks of the locomotor system are of main interest and must be located. To date, several thousand sequences have been recorded, which makes a manual ...

Objective. There are no reports comparing the protocols provided by rigid marker set (RMS) and point cluster technique (PCT), which are similar in terms of estimating anatomical landmarks based on markers attached to a segment. The purpose of this study was to clarify the correlation of the two different protocols, which are protocols for knee motion in gait, and identify whether measurement er...

We consider elastic registration of medical image data based on thin plate splines using a set of corresponding anatomical point land marks Previous work on this topic has concentrated on using interpola tion schemes Such schemes force the corresponding landmarks to exactly match each other and assume that the landmark positions are known exactly However in real applications the localization of...

In this paper, we investigate diierential approaches for the localization of 3D anatomical point landmarks in 3D medical images. First, we study an existing 2D edge intersection approach for localizing corners and theoretically analyze the localization accuracy of this method for an analytic model of an L-junction. Then, we extend this approach to 3D. We propose two two-step and one three-step ...

In order to design industrial products fitting well to the human body, it is necessary to make full use of information of human anatomical landmarks. These landmarks however cannot be extracted automatically from point cloud data of human body surface obtained by a 3D scanner. And the coordinate system for the design model cannot be decided by the point cloud itself. Our previous report propose...

This work addresses the challenging problem of parsing 2D radiographs into salient anatomical regions such as the left and right lungs and the heart. We propose the integration of an automatic detection of a constellation of landmarks via rejection cascade classifiers and a learned geometric constellation subset detector model with a multi-object active appearance model (MO-AAM) initialized by ...

Splenectomy when performed by laparoscopy is associated with less morbidity compared to open surgery. It also has a cosmetic advantage due smaller wounds. The case discussion illustrates the anatomical landmarks and relationships during laparoscopic splenectomy.
