Research on character multi-dim cognizing feature extraction and application
Zhou Yuan-yi · Journal of Anhui University of Technology and Science · 2006
A method is presented to disassemble the character into several parts,which can be recognized by the computer topologically based on the high-frequency wavelet coefficients vector,disregarding the traditional extraction method using the statistical or structural feature based on the individual pixel in the 2-dim plane of character.Moreover,the concept of multi-dim cognizing feature is put forward by encoding the character,according to the location and run-length information.The information confusion and redundancy can be largely eliminated and the improvement of the preciseness,speediness and utilities is achieved when vehicle license plate is to be recognized.
