Fig. 2From: Chronic cholestasis detection by a novel tool: automated analysis of cytokeratin 7-stained liver specimensCut-off staining intensity for K7-positive hepatocytes. Cells pointed with red arrows are considered negative, because they are stained too lightly. Thus, they are excluded from the training annotations made for the AI model. The darker brown hepatocytes circled in green were considered positive. They were annotated in the training phase to demonstrate and teach the AI model what K7-positive hepatocytes look likeBack to article page
