Generation of Moire-Like Images Using Gaussian Filter

A non-photorealistic rendering method to automatically generate moire-like images from photographic images using bilateral filter has been proposed. Moire-like images are expressed by superimposing moire-like patterns on photographic images. We propose a method to improve the conventional method and generate moire-like images using Gaussian filter, unsharp mask and inverse filter. Compared with the conventional method, the proposed method can suppress the degradation of image quality of the background photographic images of moire-like images. Moreover, the proposed method can generate moire-like patterns having a texture different from the conventional method. To verify the effectiveness of the proposed method, we conduct an experiment using several photographic images and visually confirm the results. In addition, we conduct an experiment by changing the parameter values in the proposed method and visually confirm the changes in moire-like images.
