Optimizing Operating Points for High Performance Lesion Detection and Segmentation Using Lesion Size Reweighting. (arXiv:2107.12978v2 [eess.IV] UPDATED)

There are many clinical contexts which require accurate detection and
segmentation of all focal pathologies (e.g. lesions, tumours) in patient
images. In cases where there are a mix of small and large lesions, standard
binary cross entropy loss will result in better segmentation of large lesions
at the expense of missing small ones. Adjusting the operating point to
accurately detect all lesions generally leads to oversegmentation of large
lesions. In this work, we propose a novel reweighing strategy to eliminate …
