Fig. 5From: Validation of machine learning models to detect amyloid pathologies across institutionsa The Digital Slide Archive application grants access to the HistomicsTK graphical user interface for annotation of WSI, red is the annotated region on the sample Aβ stained slide. b Gray matter regions can be difficult to delineate using immunohistochemical stains, in such cases we can use adjacent sliced tissue stained for Bielschowsky silver to guide the annotation. The annotations are saved in SVG format as metadata to the item containing the WSI in the Digital Slide Archive datastoreBack to article page
