Abstract: Eine globale Position eines observierten Objektes wird durch Beziehen einer ersten globalen Position eines observierten Objektes mit wenigstens einer Positionsbestimmungseinheit ermittelt. Es wird ein Ermitteln dahingehend durchgeführt, ob ein Satz an gespeicherten visuellen Eigenschaftsdaten wenigstens eines Wegepunktes mit einem Satz an visuellen Eigenschaftsdaten übereinstimmt, der anhand von wenigstens einem erfassten Bild bezogen wurde, das eine zu dem observierten Objekten gehörende Szene aufweist. In Reaktion auf den Satz an gespeicherten visuellen Eigenschaftsdaten, der mit dem Satz an bezogenen visuellen Eigenschaftsdaten übereinstimmt, wird eine zweite globale Position des observierten Objektes auf der Grundlage eines Satzes an gespeicherten Standortdaten ermittelt, der zu dem wenigstens einen Wegepunkt und der ersten globalen Position gehört.

Abstract: A system, method, and computer program product are described for detecting anomalies in an image. In an example embodiment the method includes partitioning 304 each image of a set of images into a plurality of image local units. The method further includes clustering 308 all local units in the image set into clusters, and consequently assigning 310 a class label to each local unit based on the clustering results, wherein the local units with identical class labels have at least one substantially related image feature. Further, the method includes assigning 312 a weight to each of the local units based on a variation of the class labels across all images in a set of images. The method further includes performing a clustering over all images in the set, for example by using a distance metric that takes the learned weight of each local unit into account, then determining the images that belong to minorities of the clusters as anomalous.

Abstract: The present system and apparatus uses image processing to recognize objects within a scene. The system includes an illumination source for illuminating the scene. By controlling the illumination source, an image processing system can take a first digitize image of the scene with the object illuminated a higher level and a second digitized image with the object illuminated at a lower level. Using an algorithm, the object(s) image is segmented from a background image of the scene by a comparison of the two digitized images taken. A processed image (that can be used to characterize features) of the object(s) is then compared to stored reference images. The object is recognized when a match occurs. The system can recognize objects independent of size and number and can be trained to recognize objects that it was not originally programmed to recognize.
