Example of a testis tissue image viewed in the QuPath system. Various regions of pathology have been human annotated in the image. The bottom image shows a zoomed in section from the top image that more clearly shows the annotations. For example, the light green annotations identify normal tubules, and the mid annotations identify atrophy. The large dark green rectangle annotates an “ignore” region.
