摘要： A wireless communication medium includes an antenna, an analog signal processor, a digital signal processor, and a central processing unit & logic module. The antenna transmits and receives a signal to and from an external apparatus. The analog signal processor converts an analog signal to a digital signal, and converts a digital signal to an analog signal. The digital signal processor demodulates the digital signal, detects the start and end of data, and generates a first control signal for determining whether data is transmitted to the external apparatus and a second control signal for perceiving the end of data, blocking the reception of data, modulating data, and determining whether modulated data is transmitted to the external apparatus. The central processing unit & logic module processes data received from and transmitted to the external apparatus. Accordingly, an efficiency of processing a RF signal can be improved.

摘要： A face recognition and apparatus are provided. According to the method, an SVM classifier is created through machine learning on the basis of a degree of similarity of a divided facial image, and a facial image to be authenticated is normalized to a predetermined size using a center between two eyes. The normalized image is divided into more than one image in horizontal and vertical directions, respectively. Next, predetermined characteristic vectors from the divided images are extracted and a similarity vector based on a degree of similarity with respect to a registered characteristic vector is created. The similarity vector is input to the SVM classifier, so that authentication is performed.

摘要： An iris recognition method is provided. In the iris recognition method, binary image data is obtained by receiving eye image data and filtering the received eye image data using a predetermined threshold value. Then, candidate center search regions are searched for finding a pupil center using profile information of rows and columns of the binarized image. a pupil boundary and a center point are detected by performing a mask operation using 8 pupil boundary mask templates for each of concentric circles formed of pointes in the searched candidate center search regions as candidate pupil centers and different radiuses. An iris boundary region is detected by performing a masking operation using 6 iris boundary mask templates corresponding to 6 locations for concentric circles formed of the pupil center as an origin and different radiuses.
