A multi-touch interface for natural and seamless image composition

Image composition is a basic process in digital image editing. Its objective is to enable convenient image object copy-and-paste to generate new images which look natural and realistic. Seamless image composition systems often require users to successively choose a rough region of the inserted object and the target location for automatic which is rather tedious for using 2D input devices like mouse. We propose a new system that efficiently combines direct multi-touch interaction with seamless image composition. In sharp contrast to previous interfaces, we develop a family of multi-touch gestures, allowing users to simultaneously operate multiple inserted objects and also to interactively edit and tune inserted objects positions and geometry. Experiments show that our system not only brings novel painting experience to users but also provides a practical and effective tool for inserted objects design.
