Susan, thanks for the post. Appears to be great potential in computer vision for this sort of application, particularly with the problem of subjectivity in human assessment. As a somewhat related sidenote, in a study published in Psychological Science (Drew, Võ, & Wolfe, 2013), radiologists were asked to examine scans of patients’ lungs and search for nodules indicative of cancer. One of the scans included an image of a gorilla that is obvious when you are looking for it, yet apparently not so obvious when you are looking for something else. Although the gorilla is 48 times the size of the typical nodule, and eye tracking showed most of the radiologists looked right at it, 83% of them failed to notice.
