Abstract

The invention relates to an adversarial sample image filtering method and device, electronic equipment and a medium, and the method comprises the steps: obtaining an original adversarial sample image which comprises interference information; performing feature extraction on the original adversarial sample image to obtain first feature information of at least two dimensions, and performing singular value decomposition on the first feature information of each dimension to obtain second feature information corresponding to the first feature information of the dimension; for the second feature information of each dimension, determining third feature information meeting a filtering condition in the second feature information according to the preset filtering condition corresponding to the dimension; and determining a target confrontation image according to the third feature information of each dimension. Through the method provided by the invention, interference information in the original adversarial sample image can be effectively filtered out.

Description
