我们提出了一种新的方法，用于将照片或图像转换为合成的绘画风格的一个例子绘画。将绘画风格的笔触视为样本纹理，我们将学习示例绘画的问题归结为纹理合成问题。该方法采用层次块为基础的方法来合成的方向性纹理。该方法的主要特点是：1）绘画风格被表示为用户从示例绘画中选择的一个或多个样本纹理块; 2）图像分割和由中轴定义的画笔笔划方向被用来更好地表示和传达合成绘画中存在的形状和对象; 3）使用图像掩模和纹理块的层次结构来有效地合成高质量的方向性纹理。通过纹理方向量化和高斯金字塔的使用，合成过程进一步加速。我们的方法有以下优点：第一，合成的笔画纹理可以遵循一个方向场所确定的形状的区域被画。第二，该方法是非常有效的;在商品PC上，合成绘画的生成时间范围从几秒到大约一分钟，而不是其他现有方法所需的几个小时。此外，这里提出的技术提供了一个新的和有效的解决方案的问题，合成一个二维方向纹理。我们使用了一些测试的例子来证明所提出的方法的效率和高质量的结果所产生的方法。
We present a new method for converting a photo or image to a synthesized painting following the painting style of an example painting. Treating painting styles of brush strokes as sample textures, we reduce the problem of learning an example painting to a texture synthesis problem. The proposed method uses a hierarchical patch-based approach to the synthesis of directional textures. The key features of our method are: 1) Painting styles are represented as one or more blocks of sample textures selected by the user from the example painting; 2) image segmentation and brush stroke directions defined by the medial axis are used to better represent and communicate shapes and objects present in the synthesized painting; 3) image masks and a hierarchy of texture patches are used to efficiently synthesize high-quality directional textures. The synthesis process is further accelerated through texture direction quantization and the use of Gaussian pyramids. Our method has the following advantages: First, the synthesized stroke textures can follow a direction field determined by the shapes of regions to be painted. Second, the method is very efficient; the generation time of a synthesized painting ranges from a few seconds to about one minute, rather than hours, as required by other existing methods, on a commodity PC. Furthermore, the technique presented here provides a new and efficient solution to the problem of synthesizing a 2D directional texture. We use a number of test examples to demonstrate the efficiency of the proposed method and the high quality of results produced by the method.
