Abstract: The present invention includes a method for processing an intensity image (J0) formed of points representing an object (LV), including steps for automatically supplying points so as to determine a minimum path representing the object contour (CT), involving:
acquiring data of the intensity image,
evaluating probability values (P) indicating the probability that a given point of the image belongs to predefined regions of the image relating to the object, and deriving a contour model (SP) of the object from said probability values (P),
transforming the image (J0) into a three-dimensional matrix image (IM) based on said contour model (SP) and said probability values (P),
performing dynamic programming (DP) in order to determine said minimum path (CT) in said three-dimensional matrix image (IM).
Abstract: In a CVD chamber (120) having a chuck (122) to hold a semiconductor substrate (100) and having a plasma generator (121) to generate a plasma (125), a trench in the substrate is filled with dielectric material from ions (126) of the plasma. The ions are forced to move in a direction (127) that is substantially perpendicular to the surface of the substrate by a pulsed unidirectional voltage between the plasma generator and the substrate, by a circular magnetic field, or by a combination of both fields.
Abstract: An image processing method for providing three-dimensional geometric modeling of the spine, using a biplanar image reconstruction, comprising steps of acquisition of a first view (F) of a part of the spine, and a second view (L) of the same part of the spine taken from a different angle around the longitudinal axis of the spine, matching the dimensions of the views (F,L) from two predetermined corresponding landmarks (P1, P2) on each view and deriving three-dimensional coordinates (z, x, y) of corresponding points (P) along the spine. Application: X-ray medical 3-D imaging.
Abstract: System for monitoring the discharging/charging cycles of a rechargeable battery which includes adaptive calculation means for providing a predictive indication of when the battery will reach a critical discharge voltage. The adaptive calculation means includes parameters which can be modified by other adaptive calculation means so as to optimize the monitor's performance depending on the battery's actual use. The adaptive calculation means may be neural networks formed by a microprocessor and memory, and the monitor system may be coupled to a host system.
