高精度壁画图像的实时浏览技术

Real-time browsing of high-precision frescos

数字化壁画图像可以广泛应用于保护修复、学术研究和旅游指导等方面,敦煌壁画数字化技术的引入将是永久无损保存敦煌艺术的最佳手段。作为壁画数字化技术的一个重要组成部分,高精度壁画的实时浏览给计算机交互显示带来了巨大的挑战。本文利用CUDA强大的并行计算能力,设计了一个基于动态分辨率的高精度壁画实时浏览算法。该算法不需要对大图像进行预处理,可以让用户很流畅地浏览不同分辨率下的高精度大图像。

Digitalized frescos are widely used in many areas,such as image impainting,art research,tourist guiding and so on.The introduction of digital image technology into Dunhuang frescos will bring the best way to permanently conserve Dunhuang art without destruction.As an important part of the technology,Real-time browsing of high-precision frescos brings us tremendous challenges.Taking advantages of parallel computing capabilities of CUDA,this paper presents an interactively image browsing algorithm based on dynamic resolution method.This algorithm avoids of burdensome pre-processing operations,while brings to users smooth viewing experience of large high-precision images.
