曲面细节的动态转移

基于图像的曲面细节转移已经被证明是一种有效祛除斑点的技术.这种技术的缺点之一是需要用户指定平滑参数σ,而且每次用户改变σ,都需要将Gaussian平滑应用到整个图像,对于大图像来说,就会很耗时.在这篇文章中,提出一种动态地转移曲面细节的技术,不需要用户指定σ,仅平滑处理须进行细节转移的区域,避免了平滑整个图像的耗时操作.

Dynamic Transfer of Surface Details

The image-based surface detail transfer has been shown to be an effective technique for blemish removal. One drawback is that it requires the user to specify the smoothing parameter sigma. Furthermore, every time the user modifies the sigma, it has to apply Gaussian smoothing to the entire image which can be time consuming for large images. In this paper, we present a technique to dynamically transfer surface details. We do not require the user to specify sigma. And we only smooth the area which is necessary for detail transfer,thus avoiding the time consuming operation of smoothing the entire images.
