A color adjustment method for automatic seamless image blending

Abstract

In this paper we present a stable automatic system for image composition, which can well control the color difference between two images, and produce a seamless composite image with color continuity. This is a userfriendly system that reduces the user's manual tasks. We observe that Poisson image editing written by Perez et al. [8] blends well for seamless boundary automatically. However, the color of user-selected region can be changed after applying this method. So the object loses its original color tone after blending. To solve this problem, firstly we check out the case of object color being changed rapidly. It can be done by calculating color temperatures of two input images and comparing the white balance with each other. Next, a distance ratio rule is applied to controls the pixels included in the region between the userselected boundary and object boundary. © Springer-Verlag Berlin Heidelberg 2007.
