In this paper, we study the problem of determining a mathematical description of the surface defined by the shape of a membrane based on an image of it and present an algorithm for reconstructing the surface when the membrane is deformed by unknown external elements. The given data are the projection on an image plane of markings on the surface of the(More)
A panel of computer vision researchers recently convened and produced a document concerning the relatively new eld of \Active Vision" 36]. Although there is no precise deenition of what active vision is, most researchers would agree that active vision is concerned with controlling camera parameters, such as position, focal length, aperture width, and so on,(More)
Traditional robot controllers are not designed to produce human-like reactive motion—movements lasting tens of sample periods and requiring large accelerations. One of the major obstacles to producing reactive motions with contemporary controllers is that they rely on kinematic commands. The performance of short duration motions requiring large(More)
Parallel processes for patterning densely packed nanometre-scale structures are critical for many diverse areas of nanotechnology. Thin films of diblock copolymers can self-assemble into ordered periodic structures at the molecular scale (approximately 5 to 50 nm), and have been used as templates to fabricate quantum dots, nanowires, magnetic storage media,(More)
Acquisition, analysis, and classification of repetitive human motion for the assessment of postural stress is of central importance to ergonomics practitioners. We present a two-threshold, multidimensional segmentation algorithm to automatically decompose a complex motion into a sequence of simple linear dynamic models. No a priori assumptions were made(More)
In recent years, flexible robotic catheter systems have been developed for minimally invasive cardiac surgery. These systems commonly include a passive flexible catheter, which is biocompatible, and an active servo system which provides the actuation for the flexible catheter. To relate control actuation motion of the servo system to catheter motion, models(More)
