摘要：
This invention describes a technology to improve the feature based comparison of images. The images are captured and their significant features are extracted. For a comparison only the feature values have to be compared instead of the images themselves. This leads to a significant reduction of storage space and calculation time needed. The reliability of the comparison is improved greatly by including also the individual variation ranges of the feature values and using a specialized neural net for classification.
