objectives: the gals (gait, arms, legs and spine) examination is a compact version of standard procedures used by rheumatologists to determine musculoskeletal disorders in patients. computerization of such a clinical procedure is necessary to ensure an objective evaluation. this article presents the first steps in such an approach by outlining a procedure to use motion analysis techniques as a ...

With the arrival of increasingly higher resolution PET systems, small amounts of motion can cause significant blurring in the images, compared to the intrinsic resolutions of the scanners. In this work, we have reviewed advanced correction methods for the three cases of (i) unwanted patient motion, as well as motions due to (ii) cardiac and (iii) respiratory cycles. For the first type of ...

For the management of a large number of motion data for humanoid virtual actors we propose to use a database system to store and retrieve motion data with additional information. We show key questions lying behind the different classification schemes for human motion. Having obtained these criteria, we deduce the requirements a database has to fulfil for coping different classification schemes....

With advances in both communication and multimedia technologies, there is a critical need to have visual management systems or user-friendly tools to assist in information retrieval from digital multimedia databases. Amongst the salient features that could be used to define visual content for example, are pixel intensity, colour, texture, shape and motion. Of these, motion is the most obvious a...
