Classification: CPC G | IPC G

Claim 3:
4. A method of training a preprocessor, the method comprising:
generating adversarial noise from a training image through an adversarial noise generator;
generating a noised training image by combining the training image and the adversarial noise;
generating defensive noise from the noised training image through a defensive noise generator;
generating a denoised noised training image by combining the noised training image and the defensive noise;
generating a denoised training image by combining the training image and the defensive noise;
determining a total loss value by inputting the denoised noised training image and the denoised training image to the classifier using a total loss function; and
training, based on the total loss value, the adversarial noise generator and the defensive noise generator.
