| 20120114216 | Microscopy Analysis Technique - A method and apparatus for the analysis of cell nuclei may use a system where images captured from a bright field microscope are analysed and information is retrieved that give quantitative information of the different type of chromatin within the cell nuclei for example Hetrochromatin and Euchromatin. The method is based on segmented cell nuclei. Quantitative information is determined related to the greyscale distribution of the different areas of the chromatin types and the object structure within these different areas. | 05-10-2012 |
| 20110274336 | OPTIMIZING THE INITIALIZATION AND CONVERGENCE OF ACTIVE CONTOURS FOR SEGMENTATION OF CELL NUCLEI IN HISTOLOGICAL SECTIONS - A computer-implemented segmentation method is used to process an image representing a plurality of nuclei. The method is implemented in a computer having a processor and a physical memory. A set of instructions are provided to the processor the physical memory of the computer. The processor is configured by executing the set of instructions in the physical memory so as to automatically segment the image by: thresholding a grey-scale image to create a black and white image; identifying objects in the black and white image and removing objects failing to meet predetermined criteria; extracting objects; and applying an edge detector on the segmented image to identify the edges of the nuclei. Overlapping nuclei are split to improve results. | 11-10-2011 |
