摘要
A system and method identify objects, such as fruits, vegetables, and images through the recognition of unique surface features represented by signals from a scanner that pass over the objects. The scanner signals are processed by applying a modified wavelet transform to them and comparing the results to previously stored data. The system uses an optical scanner, a processor that transforms the data acquired by the scanner to extract a translation invariant feature vector, and a comparator which compares the transformed signal to a predetermined set of vectors for a corresponding identification based upon the comparison set.
