Patent application numberDescriptionPublished
20100216114METHOD AND APPARATUS FOR DETERMINATION OF COMPONENTS IN ROOT CROPS - The invention relates to a process for the determination of components in root crops as well as a device for performing the process. Root crops of a plot are prepared in such a way that becomes possible, using near-infrared spectroscopy, to determine the content of substances with a high analytical accuracy and short analysis time and wherein the recorded data concerning the identity and quantity of ingredients are representative of all root crops of a plot.08-26-2010

Patent application numberDescriptionPublished
20100074539Differentiation of illumination and reflection boundaries - The present invention provides methods and apparatus for image processing in which brightness boundaries of an image are identified and analyzed in at least two, and more preferably three or more, spectral bands to distinguish illumination boundaries from reflectance boundaries. For example, in one embodiment of the invention, a brightness boundary of the image can be identified as an illumination boundary if at least two wavelength bands of the image exhibit a substantially common shift in brightness across the boundary.03-25-2010
