A method for segmenting a color image as well as digital microscope

摘要

The present invention relates to a method for segmenting a color image composed of pixels, which, for example, with a digital microscope was recorded and is to be subjected to an automatic analysis. The invention further relates to a digital microscope, with which the process according to the invention can be carried out. The method provides, first a color to select a to be segmented region of the color image represents. The colors assigned to the pixels and the selected color, according to a first color model based on three color irritate to provide. It is a measure of distance for each of the image points to determine which a distance between the selected color and the color of the respective image point according to the first color model represents. The colors assigned to the pixels and the selected color, according to a perception oriented second color model, for which purpose at least in each case a color tone for the colors assigned to the pixels and is determined for the selected color. One of the pixels is associated with the segmented region, when the assigned to the respective pixel spacing under a predeterminable threshold value and if the assigned to the respective pixel color shade in a prescribed interval around the of the selected color hue is associated with.
