Latest Patents

Wen-Gang Che holds a patent for an "Iris recognition method utilizing matching pursuit algorithm." This invention simplifies the extraction and reconstruction of iris features while reducing the memory space required for each iris feature vector, all without compromising recognition accuracy. The method includes an iris-localization component that identifies the iris region based on color differences in the eyeball. Primary iris features are extracted and transformed into a sequence of iris feature vectors using a matching pursuit algorithm. This allows the iris image to be represented by a sequence of atoms, each containing base, amplitude, and location. The final step involves comparing the feature vectors of two irises to determine if they match.
