摘要： 研究目的：通过调查不同反锯齿技术的实现方法和优缺点，为研究人员提供一种快速理解反锯齿技术的方法，并指出该领域未来研究方向。
\n文章内容：将图像反锯齿技术分为后滤波和预滤波两大类，并将后滤波技术细分为硬件反锯齿技术和后处理反锯齿技术（图1）。针对每一类技术，分析了主流反锯齿技术的实现原理和主要优缺点。在讨论每一类技术的最后，将这些技术作了归纳和比较，并阐述其应用。对后滤波技术，首先讨论了基于GPU管线的SSAA、MSAA及其不同的改进技术，接着分析了为适应延迟渲染技术而出现的独立于GPU管线的各种后处理滤波技术（以形态反锯齿技术为代表），最后从不同方面比较了主流后滤波技术间的差异（表1）。对于预滤波技术，主要依据时间发展脉络讨论了不同的解析反锯齿技术。最后，从反锯齿质量、性能、输入限制、带宽需求等方面对这两大类技术作了比较（表2)，指出了未来研究方向。

Abstract: Anti-aliasing is a well-established technique in computer graphics that reduces the blocky or stair-wise appearance of pixels. This paper provides a comprehensive overview of the anti-aliasing techniques used in computer graphics, which can be classified into two categories: post-filtering based anti-aliasing and pre-filtering based anti-aliasing. We discuss post-filtering based anti-aliasing algorithms through classifying them into hardware anti-aliasing techniques and post-process techniques for deferred rendering. Comparisons are made among different methods to illustrate the strengths and weaknesses of every category. We also review the utilization of anti-aliasing techniques from the first category in different graphic processing units, i.e., different NVIDIA and AMD series. This review provides a guide that should allow researchers to position their work in this important research area, and new research problems are identified.
Key words: Anti-aliasing    Hardware    Post-filtering    Pre-filtering    Sampling
