The objective measuring method of MRTD based on artificial neural network is using computer to judge the four bacilliform target image automatically and objectively replacing of human eyes' subjectively judgment. The characteristic vector of four bacilliform target image is extracted firstly before using computer to identify the image. The reasonable choosing of the characteristic vector not only affects the determination of the neural network, but also directly relates the identifying speed and accuracy (the judging efficiency of the neural network). The wavelet analysis of four bacilliform target image can well simulate the identifying procedure of the eye to four bacilliform target image. The experiment of identification of four bacilliform target image shows that using the total energy of the images of different frequency range as the characteristic vector is more suitable than using images average value, square-error, information entropy, etc.
