中文说明：根据结构张量能区分图像的平坦区域、边缘区域与角点区域。 此算法也算是计算机科学最重要的32个算法之一了。链接的文章中此算法名称为Strukturtensor算法，不过我搜索了一下，Strukturtensor这个单词好像是德语，翻译过来就是
English Description：
According to the structure tensor to distinguish the smooth areas of the image, edge and corner areas. This algorithm is also regarded as one of the 32 most important computer science algorithms. This algorithm name for the Strukturtensor algorithm in the linked articles, but my search a bit, Strukturtensor this word seems to be in German, which translates as structure tensor structure tensor. Here said the tensor is not a tensor in relativity or Riemannian Geometry, tensor of Riemannian Geometry, many papers are called tensor fields. Nor the field has yet to what extend the matrix of higher order tensor, tensor decomposition is mainly. Here is a matrix of the structure tensor, a organization of data structure to the image pixels.
