Interactive alpha matting technique extracts the foreground of image with limited interaction.It is widely applied to image editing,3D construction,and has high applicative value.In recent years,the Matting Laplace matrix gives the linear relation on alpha matte,and takes important roles in alpha matting.In this paper,the Moving Matting Matrix is given,which use moving least square instead of least square method,use KNN( K nearest neighbor) model instead of local neighbor model.We solve the alpha matte by Moving Matting Matrix.Experiments prove this method is effective.
