Abstract: In order to remove color spots with the method of surface detail dynamic transfer，it requires a Gaussian smoothing parameter σ which is determined by the visual inspection on the geometric module by the user.Meanwhile，every time the user changes σ，it has to apply Gaussian smoothing to the entire image that may cost a lot of time.To solve the problem，this paper puts forward a technology of surface detail dynamic transfer，which can compute σ according to the size of the color spot and just needs to apply Gaussian smoothing to a corresponding region with smaller size of the color spot.It makes the process of removing color spots on image more intelligent and much more efficient on computing.

摘要： 针对曲面细节转移在祛除图像斑点应用时，需要依赖用户对斑点几何细节模型的视觉观察确定Gaussian平滑参数σ的大小，对用户每次改变σ的取值都需要实施将Gaussian平滑应用到整个图像的耗时操作，提出了一种曲面细节动态转移的技术，它能够根据斑点的大小自动确定σ的大小，且仅需要将Gaussian平滑应用到与斑点相对应的小区域，使祛除图像斑点智能化，极大地提高了运算效率。
