““The pupil of the eye is like a black mirror,” said Jenkins. “To enhance the image, you have to zoom in and adjust the contrast. A face image that is recovered from a reflection in the subject’s eye is about 30,000 times smaller than the subject’s face.” In the research, the whole-face area for the reflected bystanders was 322 pixels on average.”
