One-Pixel Attacks Against Medical Imaging: A Conceptual Framework
Kaisa Sulasalmi
23.04.2021
This paper explores the applicability of one-pixel attacks against medical imaging. Successful attacks are threats that could cause mistrust towards artificial intelligence solutions and the healthcare system in general. Nowadays it is common to build artificial intelligence models to classify medical imaging modalities as either normal or as having indications of disease. One-pixel attack is […]
