METHOD AND DEVICE FOR DETERMINING A CELL CONTOUR OF A CELL

摘要

The invention relates to a method for determining a cell contour (110) of a cell having a nucleus (114) and cell plasma (116) in an image of the cell, comprising the determination of nucleus candidate pixels (K_i) associated with the nucleus (114). The method also comprises the determination of a pixel located on the inside of a region formed by the nucleus candidate pixel (K_i) in order to obtain a center nucleus candidate pixel (K_o), the determination of a first edge candidate pixel (P_N) as a pixel on a predetermined path (120) leading away from the center nucleus candidate pixel (P_o) by detecting a change from a first section to a second section of a color space, and the discovery of continuing edge candidate pixels starting from the first edge candidate pixel (P_N), said elements forming a boundary (122) surrounding the cell, by means of which a path finding algorithm, which tends to prefer shorter path lengths and paths by pixels in the second section of the color space.
