Kidney glomeruli-ROIs extracted from histological slides stained with HE or PAS.

<p>Kidney glomeruli-ROIs extracted from histological slides stained with HE or PAS. The multicenter test set of 78 regions of interest together with annotations. ROIs were extracted from 20 WSIs representing various human kidney pathologies. WSI&#39;s came from four sources: three independent medical centers and TCGA.&nbsp; Slides from three sources were stained with HE and slides from one center were stained with PAS. Slides were digitalized on Pannoramic 250 Flash II (3DHISTECH, Budapest, Hungary), Hamamatsu NanoZoomer S60 Digital slide scanner, or using Aperio AT Turbo (Leica Biosystems, Vista, CA). ROIs were extracted for x10, that corresponding to the pixel size ~10um.</p>
