Moreover, the method includes a step of applying a second fast marching algorithm within the homogeneous regions classified as foreground so as to segment the foreground into individual biological cells. | 12-29-2011 |
20130162803 | MOSAIC PICTURE GENERATION - A stability and, thus, also a quality of mosaic generation is improved by exploiting the advantages of global optimization while giving up performing the optimization fully on the basis of mutual alignment of the image information alone, i.e. on the basis of the result of a search for similarities, but when, additionally, information about error statistics of the capturing device, which took over portion-by-portion capturing of the object plane, is instead also taken into account in the positioning of the subimages in that a secondary constraint (secondary constraint) is set up for the capturing position variables in the optimization problem. | 06-27-2013 |
20130279789 | DEVICE AND METHOD FOR DETERMINING OBJECTS IN A COLOR RECORDING - A device for determining objects in a color recording has an identifier, a feature extractor and a classifier. The identifier is implemented to identify the connected regions whose size or shape correspond to a predetermined condition from a plurality of connected regions existing in a binary image derived from a color recording based on a size or a shape of these connected regions. The feature extractor is implemented, for each of the identified connected regions, to extract a feature set from the color recording. The classifier is implemented to classify the identified connected regions into at least two disjunct groups based on the extracted feature sets for the identified connected regions. | 10-24-2013 |

20080236430 | Method for Determining Optimized Ink Presetting Characteristic Curves for Controlling Inking Units in Printing Presses and Printing Press for Carrying out the Method - A method for determining optimized ink presetting characteristic curves for the control of inking units in printing presses through the use of a computer, includes acquiring measured values on a printing material produced by a printing press within the context of a running print job, through the use of a color measuring instrument. The acquired measured values are compared with a color set point to be achieved, fluctuations in the acquired measured values are determined and, if fluctuations lie within a defined permissible tolerance band around the color set point, the computer generates a signal to adapt and store the ink presetting characteristic curves used for the running print job. A printing press for carrying out the method is also provided. | 10-02-2008 |

Deviations of detected color measuring values from the reference values are calculated for each inking zone. The calculated deviations are compared with data stored in the computer and corresponding with causes of color problems. The computer determines causes of color problems in the inking unit and/or dampening unit by comparison with the data. | 03-18-2010 |
