VERFAHREN UND VORRICHTUNG ZUR ERMITTLUNG EINER ZELLKONTUR EINER ZELLE

摘要

A method for determining a cell contour of a cell having a cell nucleus and a cytoplasm in an image of the cell includes determining nucleus candidate pixels belonging to the nucleus. Further, the method comprises determining a pixel within the area formed by the nucleus candidate pixels for obtaining a central nucleus candidate pixel, determining a first edge candidate pixel as a pixel on a predetermined path leading away from the central nucleus candidate pixel by determining a change from a first section to a second section of a color space, and finding edge candidate pixels leading away from the first edge candidate pixel forming a boundary surrounding the cell, via a path-finding algorithm tending to prefer smaller path lengths and paths through pixels in the second section of the color space.
