Bladder cancer left, prostate cancer right. Training, validation, testing done on
top slides, with additional same-tissue testing on bottom slides. For
cross-tissue testing, top slide tested against other top slide. Viewing time
heatmap for top left bladder shown in Fig
7. Note how the top bladder has more edges than the more solid bottom
bladder, while the prostates have similar tissue texture. We believe this
impacts interpatient accuracy, shown in Fig
9.
