Two-scale image harmonious cloning

A novel two-scale decomposition-based harmonious cloning algorithm over images is presented in this paper. Different from previous methods, we first decompose the lightness channel of the image into two scales: the base layer and the detail layer. Then, we process each scale using different fashions. Finally, we use mean value interpolation to solve image cloning problem. Our cloned result matches well with the target image on the detail and is seamlessly. Our approach can obtain visually pleasing cloned result between different appearance images, which is problematic in previous image cloning methods. Experimental results demonstrate the effectiveness of our harmonious cloning algorithm.
