摘要:
A method which makes it possible to replace a reference pattern (aka texture) on a video of clothing is described. For example, a video of a T-shirt with the text “UCLA” could be edited to say “UC Berkeley” with minimal user intervention. The method is novel because it separates the problem into two parts: erasing the old texture (while properly accounting for lighting) and adding the new texture (properly deformed to appear on the shirt. This decomposition creates realistic images with simple tracking models of the cloth. It is believed that this method may be used for targeted audience sales techniques, with static or dynamic replacement images replacing images on warping or otherwise deforming surfaces, in addition to other perspective deformations. Potentially, real-time image replacements using the techniques taught here could be used for live activities or real-time video feeds.
