Orientation Spectral Resolution Coding for Pattern Recognition

Multi-frame Super Resolution for Improving Vehicle Licence Plate Recognition

License plate recognition (LPR) by digital image processing, which is widely used in traffic monitor and control, is one of the most important goals in Intelligent Transportation System (ITS). In real ITS, the resolution of input images are not very high since technology challenges and cost of high resolution cameras. However, when the license plate image is taken at low resolution, the license...

Iris Pattern Classification Combining Orientation Recognition

The importance of personal authentication is gradually increasing with the development of the information society. Biometrics identification technology plays an important role in cyberspace. Unlike other biometrics such as the face or fingerprints, iris recognition has high reliability for personal identification. Iris recognition methods are classified into four categories: the phase-based met...

Songbirds use spectral shape, not pitch, for sound pattern recognition.

Humans easily recognize "transposed" musical melodies shifted up or down in log frequency. Surprisingly, songbirds seem to lack this capacity, although they can learn to recognize human melodies and use complex acoustic sequences for communication. Decades of research have led to the widespread belief that songbirds, unlike humans, are strongly biased to use absolute pitch (AP) in melody recogn...

Comprehensive analysis of spectral minutiae for vein pattern recognition

Similar to biometric fingerprint recognition, characteristic minutiae points – here endand branch points – can be extracted from skeletonized veins to distinguish individuals. An approach to extract those vein minutiae and to transform them into a fixed-length, translation and scale invariant representation where rotations can be easily compensated is presented in this paper. The proposed solut...
