1. A method comprising: capturing imagery including one or more objects in front of a green or blue-screen backdrop, wherein the green or blue-screen backdrop comprises a first steganographic orientation component embedded therein, wherein the first steganographic orientation component helps make a watermark robust to geometric distortion, wherein the captured imagery includes a representation of the first steganographic orientation component, and wherein the first steganographic orientation component is machine-readable from analysis of the captured imagery; determining a relative depth or a spatial distance between one of the one or more objects and the green or blue-screen backdrop via the first steganographic orientation component and a second steganographic orientation component, wherein the one of the one or more objects comprises the second steganographic orientation component thereon; and aligning graphic data with the captured imagery based upon the first steganographic orientation component.
