[0045] In order to make the purpose of the present invention, technical scheme and advantage expression more clearly, below in conjunction with accompanying drawing ( Figure 1-Figure 6 ) and specific implementation steps describe the present invention in detail, but not as a limitation of the present invention.
[0046] The digital image adversarial sample defense method based on truncated singular value and pixel interpolation proposed by the present invention is based on matrix singular value and pixel interpolation processing in matrix theory. The singular value of a certain threshold is discarded at the same time as the singular value smaller than the threshold, so as to retain as much important information in the image as possible. We also consider increasing the robustness and unpredictability of the defensive model, i.e. adding a step of pixel interpolation to defend against black-box attacks. Finally, after the gradient retains the singular value and performs pixel i...
