A method is disclosed for classifying plant embryos according to their
quality using a logistic regression model. First, sets of image or
spectral data are acquired from plant embryos of known quality,
respectively. Second, each of the acquired sets of image or spectral data
is associated with one of multiple class labels according to the
corresponding embryo's known quality. Third the sets of image or spectral
data values are filtered to provide filtered image or spectral data
values. Fourth, a classification algorithm, e.g., a logistic regression
analysis is applied to the filtered data values and their corresponding
class labels to develop a classification model. Fifth, image or spectral
data are acquired from a plant embryo of unknown quality, and filtered
data values are derived therefrom. Sixth, the classification model is
applied to the filtered data values for the plant embryo of unknown
quality to classify the same.
