Abstract
Roughly described, a method for estimating a size measurement of a subject feature on a body, for use with a photo, snapped by a camera which may be handheld. A reference marker is placed on the body near the subject feature. The reference marker includes concentric rings to help confirm its identify, and registration markings to determine the pose at which the photo was taken. The registration markings can be dots at vertices of a square. The method can include detecting concentric ellipses in the photo corresponding to the concentric circles, detecting the registration markings in the photo within a predetermined region which is outside the detected ellipses, geometrically transforming at least the subject feature in the photo based on the detected locations of the registration markings, calculating the scale of the photo based on the detected registration markings, and providing the transformed image and scale for the size measurement.
