1. A method for classifying a plurality of object image regions of an object to be detected using a scanning microscope, comprising: labeling each of the image areas of the object with a different respective marker so that respective light of a respective characteristic emanates from each respective marker; detecting a respective intensity of the respective light from each respective marker using at least two channels so as to generate respective detection signals, each respective detection signal being a function of the respective intensity of the respective detected light; and classifying the object regions using ratios of the respective detection signals.
