Abstract
Accurate annotation of anatomical structures or pathological changes in microscopic images is an important task in computational pathology. Crowdsourcing holds promise to address this demand, but so far feasibility has only be shown for simple tasks and not for high-quality annotation of complex structures which is often limited by shortage of experts. Third-year medical students participated in solving two complex tasks, labeling of images and delineation of relevant image objects in breast cancer and kidney tissue. We evaluated their performance and addressed the requirements of task complexity and training phases. Our results show feasibility and a high agreement between students and experts. The training phase improved accuracy of image labeling.
