Augmenting photographs with textures using the Laplacian pyramid
We introduce a method to stylize photographs with auxiliary textures, by means of the Laplacian pyramid. Laplacian pyramid coefficients from a synthetic texture are combined with the coefficients from the original image by means of a smooth maximum function. The final 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 fine-scale details. Further, we extend patch-based texture synthesis to include a guidance channel so that texture structures are aligned with an orientation field, obtained through the image structure tensor.
