We introduce a method to stylize photographs with auxiliary textures, by means of the Laplacian pyramid. Laplacian pyramid coecients from a synthetic texture are combined with the coecients from the original image by means of a smooth maximum function. The nal result is a stylized image which maintains the structural characteristics from the input, including edges, color, and existing texture, while enhancing the image with additional ne-scale details. Further, we extend patch-based texture synthesis to include a guidance channel so that texture structures are aligned with an orientation eld, obtained through the image structure tensor.
