摘　　要：针对现有的图像风格化方法中内容与风格不匹配而导致风格化效果较差的问题,在分析快速图像风格化方法的基础上,提出一种空间控制的快速图像风格化方法(FSTSC)。将图像分为多个小块(patch),使用块匹配方法寻找风格图像和内容图像最匹配的patch。利用图像语义分割方法对图像进行预处理,根据不同内容类别的引导向量计算语义风格损失,控制内容图像的不同内容区域获得对应的风格化处理,从而提升图像风格化的效果。实验将该方法与现有的快速图像风格化方法在图像风格化效果和时间两方面进行对比,分别提升约12.5%和25.5%,表明该方法是一种合理和有效的方法。To solve the problem of poor image style transfer effect of existing image style transfer methods caused by the mismatch between content and style,based on the analysis of fast image style transfer method,this paper proposes a fast image style transfer method based on spatial control(FSTSC).It divided the image into multiple patches and used the patch matching method to find the best matching patch between style image and content image.Then the semantic segmentation method was used to preprocess the image,calculated the semantic style loss according to the guidance vector of different content categories,and controlled the different content regions of the content image to obtain the corresponding style transfer processing,thus improving the image style transfer effect.In the experiment,this method was compared with the existing fast image style transfer method in terms of image style transfer effect and time,which improved about 12.5%and 25.5%respectively.The results show that this method is reasonable and effective.
