Patent number: 7801405Abstract: An image free from interfering structures may be generated by means of a fiber bundle of several optical fibers, when for the system of fiber bundle and sensor imaging parameters are provided, which describe the geometrical characteristics of the intensity course generated by each individual optical fiber on the sensor. In image reconstruction, for each individual optical fiber an amplitude value and/or luminosity information may be generated by fitting a function of the amplitude value and the imaging parameters of the respective optical fiber to an intensity picture of the sensor, so that an optimum amplitude and/or luminosity value may be generated considering the geometrical imaging characteristics for each individual optical fiber.Type: GrantFiled: March 13, 2007Date of Patent: September 21, 2010Assignees: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V., Friedrich-Alexander-Universitaet Erlangen-NuernbergInventors: Volker Daum, Klaus Spinnler, Robert Couronné, Matthias Elter, Stephan Rupp, Christian Winter

Patent number: 7257243Abstract: A method for the analysis of a biological sample for determining a change thereof relative to a healthy biological sample includes creating a first image of the biological sample at a first acquisition modality and creating a second image of the biological samples at a second acquisition modality. The first image is classified on the basis of a first pre-determined parameter, and the second image is classified on the basis of a second pre-determined parameter, the first image being classified independently of the second image. Then, depending on the classification results, it is determined if the biological sample comprises a change relative to a healthy biological sample.Type: GrantFiled: May 14, 2002Date of Patent: August 14, 2007Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Robert Schmidt, Thomas Wittenberg, Heinz Gerhaeuser, Klaus Spinnler

Publication number: 20050202404Abstract: In a method for separating a cell group contained in an image of a sample into individual cells for a subsequent classification of the sample, wherein the cell group has a plurality of mutually overlapping cells, first a cell nucleus of a first cell which is to be separated from the cell group is selected, wherein the cell nucleus is located adjacent to a cell nucleus of a second cell. The cell plasma of the first cell and the cell plasma of the second cell overlap such that a common cell plasma is formed. Subsequently, a contraction of the common cell plasma between the cell nucleus of the first cell and the cell nucleus of the second cell is determined. At the contraction, a separation of the common cell plasma is performed. Subsequently, an area of the common cell plasma is determined in which the overlapping of the cell plasmas of the two cells is expected.Type: ApplicationFiled: October 20, 2004Publication date: September 15, 2005Inventors: Thomas Wittenberg, Matthias Grobe, Robert Couronne, Heiko Kuziela, Christian Muenzenmayer, Klaus Spinnler, Paulus Dietrich
