摘　　要：在非物质文化遗产的获取和利用过程中,经常需要对非物质文化遗产进行各个角度的视频拍摄,而由于拍摄过程中的光照原因,总有各种软阴影存在,为了去除和编辑这些软阴影,我们提出了一个基于监督学习的阴影编辑方法.该方法没有假设存在本影的特殊模型,也没有用统一的模式去处理整块阴影,而是给用户完全的控制权任其选择那块区域需要修改.我们还可以处理一些先前技术做不到的复杂情况,比如整个阴影全是半影,这是常有的事（比如树叶的阴影投射在地面上）.我们的技术需要的用户交互仅仅是大概地确定图片的哪块区域是需要修改的.随后系统即初始化,然后应用我们的模型.一旦阴影面被计算出来,用户就可以交互式地操作它们,或者用我们的简单界面修改其余部分的图片.In the process of acquisition and utilization of intangible cultural heritage, videos captured from different angles on intangible cultural heritage are always needed. But due to the insufficient illumination, there are all kinds of soft shadows on the videos. In order to remove and edit these soft shadows, we put forward to a method of shadow editing based on supervised learning. The method neither assumes the existence of umbra special model nor a unified model to deal with the whole piece of shadow, but provides the user with the complete control who are allowed to choose the area which needs modifying. We also can handle some complex problems that those previous technologies can＇t do, for example the shadows are all penumbra, as is often the case （such as the projection of the shadow of the leaves on the ground）. Our technology requires user interaction of determining which area of the image needs to be modified. Then the system is initialized at once, then our model is applied. Once the shadow side is calculated, the user can interactively operate them, or use our simple interface to modify the rest of the images.
