[Purpose] Severe calcaneus misalignment is correlated with low back pain, and affects pelvic alignment. However, little has been published with regard to the influence of pronation and supination on trunk alignment. Therefore, the present study aimed to investigate the influence of calcaneal inversion on pelvic and trunk alignment. [Subjects and Methods] A 3-dimensional motion analysis system w...

This tutorial reviews image alignment and image stitching algorithms. Image alignment (registration) algorithms can discover the large-scale (parametric) correspondence relationships among images with varying degrees of overlap. They are ideally suited for applications such as video stabilization, summarization, and the creation of large-scale panoramic photographs. Image stitching algorithms t...

OBJECTIVE This study was designed to address a recurring observation in our centre that, despite a satisfactory postoperative radiographic limb alignment, some patients are dissatisfied with the alignment and appearance of their operated leg. We carried out a prospective survey to determine patient perception of limb alignment after total knee arthroplasty (TKA) and whether level of satisfactio...

We present a complete system for automatic alignment and calibration of a stereo pan-tilt camera platform on a mobile robot. The system uses visual data from one or two controlled rotations of the head, and a single forward motion of the robot. We show how the images alone provide head alignment information, camera calibration, and head geometry. We also discuss automatic zeroing of steering an...

The following paper introduces a low bitrate video coding method on the basis of 3D motion compensated wavelet transform and SPIHT algorithm. In contrast to the conventional algorithms applying motion compensation and differential coding, here wavelet transform is used to exploit the opportunities of time redundancy. For coefficient collection, the 3D version of SPIHT algorithm was selected fro...

Sprite coding, accepted by the emerging MPEG-4 standard is a very efficient method for representing the background video object. Still this sprite generation is an open issue due to the foreground objects which obstructs the accuracy of camera motion estimation and blurs the generated sprite. In this paper we propose a method for constructing the background sprite with partial decoding of the M...

The custom-fit approach to total knee arthroplasty in conjunction with removal of osteophytes and preservation of ligaments rapidly returned function; restored motion, stability, and postoperative mechanical axis alignment; effected high patient satisfaction; and had an acceptable clinical outcome.
