在最近的年里,处理方法的基于几何学的图象和录像引起了重要兴趣。这份报纸从四个方面考虑进步:几何特征和形状,几何转变,嵌入的几何结构,和微分几何学方法。当前的研究趋势也被指出。
In recent years, geometry-based image and video processing methods have aroused significant interest. This paper considers progress from four aspects: geometric characteristics and shape, geometric transformations, embedded geometric structure, and differential geometry methods. Current research trends are also pointed out.
