Impressionist painterly style transfer based on texture localization

Most conventional example-based texture transfer methods have taken a pixel- or patch-based approach to synthesizing the output results [Hertzmann et al. 2001; Lee et al. 2010; Wang et al. 2004]. A patch of the source example, which must be big enough to provide useful information, can express a localize "mixture of vision" by itself only. The patch-based approach might suit an Impressionist painterly style transfer, but most texture transfers use only the luminance values during synthesis and keep all other color components of the target image unchanged. Color expression is one of the most important factors for Impressionist paintings, so ideally the separation of luminance values from the other color components of a source example should be avoided. In this paper, we propose a patch-based texture transfer using both the luminance and the color values of a source image. Experimental results showed that the proposed method can produce an output result visually quite similar to the Impressionist painting source.
