Creating image mosaics with a surrounding matching scheme

The usual methods of generating image mosaics suffer from abrupt color change where the color varies little in the source image, and from discontinuity of texture or shape where they are continuous in the source image. Our proposed method is based on wavelet transforms. It not only considers the similarity between a single tile and the corresponding original grid image, but also takes into account the match of surrounding tiles. The results of our experiments show that color changes are gentler in areas with similar colors originally, shapes are smoother, and textures are more refined in our image mosaics.
