Ultrasound images of muscle fascicles have been widely used to investigate muscle properties under static/dynamic and pathologic conditions. Fascicle images are usually detected and measured manually, which is subjective and time consuming, especially when dealing with large number of images. In this study, an automatic linear extraction method based on localized Radon transform and revoting strategy...
Development has continued with intrinsic feature optical motion tracking for awake animal imaging to measure 3D position and orientation (pose) for motion compensated reconstruction. Prior imaging results have been directed towards head motion measurement for SPECT brain studies in awake unrestrained mice. This work improves on those results in extracting and tracking intrinsic features from multiple...
This paper describes an upper-body human motion capture system which combines a learning-based algorithm for human torso posture recognition with a model-based approach which estimates the human arms pose. The system uses a skin colour tracker to capture the movement of hands and face, and stereo data to obtain the silhouette of the human. The disparity map generated by the stereo vision system is...
