TL;DR
This paper introduces a fast, closed-form method for photorealistic image stylization that produces spatially consistent, artifact-free stylized images more preferred by humans compared to previous methods.
Contribution
The paper presents a novel two-step approach with closed-form solutions for stylization and smoothing, improving quality and efficiency over existing techniques.
Findings
Produces more photorealistic stylizations preferred by human subjects
Runs significantly faster than competing methods
Ensures spatial consistency and reduces artifacts
Abstract
Photorealistic image stylization concerns transferring style of a reference photo to a content photo with the constraint that the stylized photo should remain photorealistic. While several photorealistic image stylization methods exist, they tend to generate spatially inconsistent stylizations with noticeable artifacts. In this paper, we propose a method to address these issues. The proposed method consists of a stylization step and a smoothing step. While the stylization step transfers the style of the reference photo to the content photo, the smoothing step ensures spatially consistent stylizations. Each of the steps has a closed-form solution and can be computed efficiently. We conduct extensive experimental validations. The results show that the proposed method generates photorealistic stylization outputs that are more preferred by human subjects as compared to those by the…
