Abstract:

A three dimensional reconstruction of vessel trees from rotational digital subtraction angiogram sequences is described. The goal of the process is to estimate the probability that each voxel contains a vessel using the projection data. The system utilizes x-ray angiographic equipment capable of producing rotational digital subtraction angiogram sequences. Reconstruction of the geometry of the vasculature is based on the projection images. The reconstructed geometry is then displayed on a screen or used for measuring specific physiological parameters. The Dempster-Shafer theory of evidence is used to combine information about location of the vessels from the different projections contained in the digital subtraction angiogram sequence.

Abstract:

A detection system identifies a person by rapidly analyzing an image frame from a video camera for the presence of a face by reducing the image in resolution and normalizing the image to compensate for lighting changes and compares the normalized image with a background image to produce a binary interest mask. The most likely position of a face is then determined by identifying a top, bottom and sides of a possible head region to define a bounding box, normalizing the pixel data within the bounding box to further compensate for lighting variations, and resizing the box to match identification templates stored in memory. The best match from the identification templates is provided with a score indicative of the degree of the match. If the score does not exceed a first score threshold, then no face is assumed present. If the score exceeds a first and second score threshold, then a face is assumed present.
