| Abstract: | This paper elaborates on how to apply genetic algorithms to calculate the binarization threshold value of the fingerprint image. It explains the chromosome decoding method, illustrates how to produce the initiate population, expounds the expressions of fitness function concerned, and ends with an illustration of the implementations of selection operator, crossover operator and mutation operator. It is proved through algorithm implementation that binarization with threshold value through genetic algorithms can achieve excellent effect. |
