Unsupervised Lesion Detection via Image Restoration with a Normative Prior

no code implementations • 30 Apr 2020 • Xiaoran Chen, Suhang You, Kerem Can Tezcan, Ender Konukoglu

In this work, we approach unsupervised lesion detection as an image restoration problem and propose a probabilistic model that uses a network-based prior as the normative distribution and detect lesions pixel-wise using MAP estimation.
