Dual-branch autoencoder network for attacking deep hashing image retrieval models
Published 2023-11-01“…Due to its powerful representation learning capabilities and efficient computing capabilities, deep learning-based hashing (deep hashing) methods are widely used in large-scale image retrieval.However, there are less studies on the security of deep hashing models.A dual-branch autoencoder network (DBAE) to study targeted attacks on such retrieval was proposed.The main goal of DBAE was to generate imperceptible adversarial samples as query images in order to make the images retrieved by the deep hashing model semantically irrelevant to the original image and relevant to the target image.Numerous experiments demonstrate that DBAE can successfully generate adversarial samples with small perturbations to mislead deep hashing models, and italso verifies the transferability of these perturbations under various settings.…”
