  • Patent number: 8478040
    Abstract: The present invention deals with an identification apparatus (100) in a video surveillance system for identifying properties of an object captured in a video sequence by a video surveillance camera. The identification apparatus comprises: an object identification unit (102) for identifying a specific object in a video sequence; a color histogram generator (104) for generating a color histogram in at least two dimensions of a color space based on color and intensity information of the specific object identified in the video sequence, the color and intensity information originating from a plurality of images of the video sequence; and an object properties identificator (106) for identifying properties of the object based on the generated color histogram. The identified properties can then be used in a tracking device (200) of the video surveillance system for tracking an object between different video sequences, which may be captured by two different video surveillance cameras.

  • Patent number: 6590612
    Abstract: An image processing system for optical systems including microscopes which separately captures (grabs) different portions of the electromagnetic spectrum as emitted from an object as separate images. Each of the separate images are individually focused and then aligned with the other images to produce a composite image. In one embodiment, the different portions correspond to red, green, and blue and the composite image is displayed to the user on as a monitor without any need for an eyepiece.
