Abstract
A computer-implemented method for scaling an image is described. An image that depicts a device in contact with a user is obtained. The image depicts identifying information that is being displayed on a display of the device. A type of the device is identified based on the identifying information. A size of the device is determined based on the identified type of the device. At least a portion of the depiction of the user is scaled based on the determined size of the device.
