Towards CGAN-based Satellite Image Synthesis with Partial Pixel-Wise Annotation

no code implementations1 Feb 2023 Hadi Mansourifar, Steven J. Simske

We first define the problem of image synthesis using partially annotated data, and we discuss a scenario in which we face such a challenge.

GAN-Based Object Removal in High-Resolution Satellite Images

no code implementations24 Jan 2023 Hadi Mansourifar, Steven J. Simske

GAN-based approaches have been employed to create forged images with two major problems: (i) adding a new object to the scene to hide a specific object or region may create unrealistic merging with surrounding areas; and (ii) using masks on color feature images has proven to be unsuccessful in GAN-based object removal.

RAF: Recursive Adversarial Attacks on Face Recognition Using Extremely Limited Queries

no code implementations4 Jul 2022 Keshav Kasichainula, Hadi Mansourifar, Weidong Shi

In this paper, we propose recursive adversarial attack on face recognition using automatic face warping which needs extremely limited number of queries to fool the target model.

Vulnerability of Face Recognition Systems Against Composite Face Reconstruction Attack

no code implementations23 Aug 2020 Hadi Mansourifar, Weidong Shi

In this paper, we prove that, the face reconstruction attacks based on composite faces can reveal the inefficiency of rounding policy as countermeasure.

One-Shot GAN Generated Fake Face Detection

no code implementations27 Mar 2020 Hadi Mansourifar, Weidong Shi

As the quality of fake faces increases, the trained models become more and more inefficient to detect the novel fake faces, since the corresponding training data is considered outdated.
