  Style transfer aims to render the style of a given image for style reference
to another given image for content reference, and has been widely adopted in
artistic generation and image editing. Existing approaches either apply the
holistic style of the style image in a global manner, or migrate local colors
and textures of the style image to the content counterparts in a pre-defined
way. In either case, only one result can be generated for a specific pair of
content and style images, which therefore lacks flexibility and is hard to
satisfy different users with different preferences. We propose here a novel
strategy termed Any-to-Any Style Transfer to address this drawback, which
enables users to interactively select styles of regions in the style image and
apply them to the prescribed content regions. In this way, personalizable style
transfer is achieved through human-computer interaction. At the heart of our
approach lies in (1) a region segmentation module based on Segment Anything,
which supports region selection with only some clicks or drawing on images and
thus takes user inputs conveniently and flexibly; (2) and an attention fusion
module, which converts inputs from users to controlling signals for the style
transfer model. Experiments demonstrate the effectiveness for personalizable
style transfer. Notably, our approach performs in a plug-and-play manner
portable to any style transfer method and enhance the controllablity. Our code
