1. A method comprising: receiving a two dimensional (2D) image frame; receiving three dimensional (3D) image data corresponding to the 2D image frame; using the 3D image data corresponding to the 2D image frame, transforming the 2D image frame; and using the 3D image data corresponding to the 2D image frame, scaling the 2D image frame, wherein the transforming and scaling results in a normalized 2D image frame, wherein the normalized 2D image frame is a scaled and transformed version of the 2D image frame, further wherein the scaling and transforming is performed using a computer.
