非真实感渲染技术的最新进展为图像到漫画的自动转换提供了最大的便利。然而,我们正面临着一个困境,细粒度的漫画转换算法总是涉及计算密集型过程(如图像过分割,暴力特征匹配,和能量优化),这使得它不适用于实时应用。另一方面,可用于智能手机的商业漫画应用程序通常依赖于简单的边缘检测和半色调或阴影。虽然处理可以在几秒钟内完成,但转换质量还不令人满意。在本文中,我们提出了MangaWall自动转换和组织照片到漫画页面。我们的目标是建立一个轻量级的漫画渲染框架,以及生成高质量的图像。为了实现这一点,漫画结构增强基于流的DoG操作和图像矢量化。然后提出了一种多层色调映射和对比度感知的半色调方法来渲染漫画般的屏幕图案。此外,对于多图像输入,一个完整的基于二叉树的布局表示,有效地组织漫画图像到同一个页面画布。我们的MangaWall可以应用于实时应用。在笔记本电脑上将1024 × 768图像转换为漫画需要不到0.7秒。
Recent advances in non-photorealistic rendering provide the best convenience for automatic image to manga conversion. However, we are facing a dilemma that the fine-grained manga conversion algorithms always involve computation intensive processes (e.g. image over-segmentation, brute-force feature matching, and energy optimization), which make it inapplicable to real-time applications. On the other hand, commercial manga Apps available for smart phones usually rely on simple edge detection and halftoning or hatching. Although the processing can be finished in several seconds, the conversion quality is not satisfactory yet. In this paper, we propose MangaWall to automatically convert and organize photos into manga pages. Our goal is to establish a lightweight manga rendition framework as well as generate high-quality images. To achieve this, the manga structure is enhanced by flow-based DoG operation and image vectorization. A multi-layer tone mapping and contrast-aware halftoning method is then proposed to render the manga-like screentone patterns. Besides, for multi-image input, a full binary tree-based layout representation is employed to efficiently organize manga images onto the same page canvas. Our MangaWall can be applied to real-time applications. It takes less than 0.7 second to convert a 1024 × 768 image into manga on Laptop PC.
