Fig. 3.

Illustration of poor image quality explanations that can be detected by ImageQX. (a) Bad framing: the image was not centered on the lesion. (b) Bad light: the lighting conditions in which the image was taken were too dark or too bright. (c) Blurry: the image is not focused on the lesion, masking out its details. (d) Low resolution: the image was taken with a low-resolution camera and few details can be discerned. (e) Too far away: few lesion details could be seen owing to the distance from the camera.
