Schematic overview of data annotation and deep learning pipeline. NFT are annotated using whole slide images, marking rectangular areas with complete annotations of NFT objects to give a visual context of NFT against the background. Image patches are extracted for network training that generates pixel-wise segmentations for NFT and background. Performance is determined using a separate novel set of images (test set) by comparing expert annotation with the trained network. Quantitative evaluation on unseen test slides provides a characterization of the behavior of the trained network in terms of robustness, reliability, and reproducibility
