Abstract

Image-based customization that incorporates personalized text strings into photorealistic images in a natural and appealing way has been of great interest lately. We describe a semi-automatic approach for replacing text on cylindrical surfaces in images of natural scenes or objects. The user is requested to select a boundary for the existing text and align a pair of edges for the sides of the cylinder. The algorithm erases the existing text, and instantiates a 3-D cylinder forward projection model to render the new text. The parameters of the forward projection model are estimated by optimizing a carefully designed cost function. Experimental results show that the text-replaced images look natural and appealing.
