The invention relates to a method for classifying spectra of objects having complex information content after recording of the spectra involving the use of a method for preprocessing data and of a method, associated with the data preprocessing, for classification with the calculation of a classifier. After the recording of the spectra and the preprocessing of the spectra, a multiple classification method is thereby performed with at least two different methods for the data preprocessing of the spectra and the method, assigned to the respective data preprocessing, for classification. After the recording and the data preprocessing of the spectra, the following steps are thereby carried out: a calculation of multiple classifiers of the series per type of data preprocessing; a determination of the classifiers of the series with iterative adjustment and validation; a calculation of probabilities of the class association, with all classifiers of the series or classifiers being equally incorporated into the determination of a classification result.

To determine the sex of a bird egg, a hole is produced at the blunt end of the bird egg, wherein the hole affects the calcareous shell and the outer shell membrane, whereas the inner shell membrane remains intact. In the region of the hole at the blunt end, beneath the intact inner shell membrane, at least one blood vessel is registered and the blood therein is excited by means of a preset incident radiation, the back-scattered radiation of which blood is measured, detected and evaluated for the sex determination.

A method for in-ova fertilisation determination and gender determination on a closed egg. The aim is to specify a method for the in-ovo fertilisation determination and gender determination on a closed egg. This aim is achieved by a method in which a closed egg is positioned, candled and/or illuminated, next an image of the closed egg is recorded, then the captured data are evaluated and the position of the cardiovascular system located in the egg is calculated. A detection unit is adjusted via the calculated position of the cardiovascular system by means of a positioning unit and subsequently the blood is stimulated, then the blood-specific and blood-foreign absorption spectra are detected and selected, the fertilisation is ascertained and then the spectra containing blood-foreign information are compensated by a compensation method and the spectra are classified for sex determination.
