Impressionist Painterly Style Transfer Based on Texture Localization

彬彬

1 Introduction

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.

2 Proposed method

The proposed method requires two input images: a source example

and a target image, as shown in Fig. 1. First, the target is represented

as a set of blocks divided recursively using an edge-based

distance transform [Hara et al. 2005]. Second, a user chooses one

or more initial seed patches from the source and manually assigns

them to various places on the target. Third, the minimization of

Eq. (1) automatically determines which source patches to assign

to which neighbors. The seeds thus grow and expand on the target.

For the neighbors of the expanded seeds, Eq. (1) is iterated

to assign additional source patches, and the resulting image is then synthesized.
