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.

Abstract: An image of a subject or a patient is displayed on a computing device. A body map overlay is displayed over the image. The body map comprises a plurality of body regions. Tapping a selected body region captures the image displayed and automatically tags the captured image with information regarding the body region that was captured. The image can subsequently be sent to a central database where a plurality of such images can be stored and later retrieved. The images can be indexed by body region or other parameters such as time, date, location, etc. The mobile application can also be used to access the database and show the images which may be ordered by body region or the other parameters.
