Amicable Aid: Perturbing Images to Improve Classification Performance

ICASSP 2023accepted

While adversarial perturbation of images to attack deep image classification models pose serious security concerns in practice, this paper suggests a novel paradigm where the concept of image perturbation can benefit classification performance, which we call amicable aid. We show that by taking the…

Just One Moment: Structural Vulnerability of Deep Action Recognition Against One Frame Attack

ICCV 2021poster

The video-based action recognition task has been extensively studied in recent years. In this paper, we study the structural vulnerability of deep learning-based action recognition models against the adversarial attack using the one frame attack that adds an inconspicuous perturbation to only a sing…

Efficient Deep Learning-Based Lossy Image Compression Via Asymmetric Autoencoder and Pruning

ICASSP 2020accepted

Recently, deep learning-based lossy image compression methods have been proposed. However, their efficiency in terms of storage and computational costs has not been addressed adequately. In this paper, we propose efficient lossy image compression methods based on asymmetric autoencoder and decoder p…

Evaluating Robustness of Deep Image Super-Resolution Against Adversarial Attacks

ICCV 2019poster

Single-image super-resolution aims to generate a high-resolution version of a low-resolution image, which serves as an essential component in many image processing applications. This paper investigates the robustness of deep learning-based super-resolution methods against adversarial attacks, which…
