这是一个关于SIFT算法介绍的pdf和ppt的合集，可以很好地帮助初学者了解sift算法。（中英文都有）-This is a collection of pdf and ppt about SIFT algorithm. I believe it can greatly help beginners to understand SIFT algorithm.

Abstract—A novel image watermarking algorithm against geometric attacks is proposed to solve watermarking synchronization problems. In watermark embedding, firstly, watermark is embedded into host image by a Single Value Decomposition (SVD) m

采用sift算法的全景图拼接技术的改进，讲解的很详细。如果pdf打不开，就用CAJvieweru-Improved algorithm using sift panorama stitching techniques, explain in great detail. If pdf open, use CAJvieweru
