最后说下Alpha通道的拉普拉斯融合,这也是个老算法了,应该比我的年龄都要大了,研究这个方向的作者一大堆(E. H. Adelson | C. H. Anderson | J. R. Bergen | P. J. Burt | J. M. Ogden),论文也有一堆,讲的比较详细的是这篇Pyramid methods in image processing(E. H. Adelson | C. H. Anderson ...

Therefore, it is of great significance to study the registration of optical and SAR images in image processing and analysis, image fusion, computer vision and other fields3. Registration algorithms can be divided into gray based registration algorithm and feature-based registration algorithm. The ...
Image matching refers to the process of identify homonymy points between two or more images by a certain algorithm. Generally speaking, Image matching technology is of important, not only in the application of image processing technology, but also in the field of pattern information. Besides, it ...
