We find that in the natural image domain, CSR behaves on par with the supervised one on several perceptual tests as a metric, and in the medical domain, CSR better quantifies perceptual similarity concerning the experts' ratings.
Most commonly, the anomaly detection model generates a "normal" version of an input image, and the pixel-wise $l^p$-difference of the two is used to localize anomalies.

To approximate human quality ratings on scarce expert data, we train surrogate quality estimation models.

We leverage direct set-based object prediction and incorporate the interaction among the objects to learn an object-relation representation jointly.

Current treatment planning of patients diagnosed with a brain tumor, such as glioma, could significantly benefit by accessing the spatial distribution of tumor cell concentration.
First, it is time-consuming - the clinician needs to scan through several slices of images to ascertain the region of interest before deciding on what severity grade to assign to a patient.

In this study, we explore quantitative correlates of qualitative human expert perception.
Exploiting learning algorithms under scarce data regimes is a limitation and a reality of the medical imaging field.
Multi-organ segmentation in whole-body computed tomography (CT) is a constant pre-processing step which finds its application in organ-specific image retrieval, radiotherapy planning, and interventional image analysis.
