Abstract: In this paper, we present a portable interactive system for image completion with perspective constraint. Image completion arises in many image filling and editing problems, but it is seldom applied in the scenario regarding to the features of perspective. In our system, basic perspective information can be obtained through user interaction in 2D on a single image, simply through picking up a few points on the image. We propose a constraint method, by building up a perspective mesh, to convey perspective structure in the whole workflow. Instead of using the common approaches in image completion, image inpainting and texture synthesis, we employ image warping to fulfill the filling process. The method is proven to be more rational for generating better visual result. Our image completion technique is portable, user-friendly and can be used to achieve good visual consistency in the perspective constrained filling tasks. We demonstrate the validity of our method by various images and applications.
