1. A method comprising: accessing alpha image data of an alpha frame generated from an alpha portion of a scene; accessing beta image data of a beta frame generated from a beta portion of the scene, the alpha frame and the beta frame having an overlapping region; generating a plurality of alpha-beta pairs for the overlapping region, each alpha-beta pair comprising an alpha value of the alpha image data and a beta value of the beta image data that both correspond to the same portion of the scene; and applying a function to each alpha-beta pair to determine first frame image data for the overlapping region, the first frame image data comprising information to generate a first frame of the scene.
