Sift descriptor matching

Webnary Local Image Descriptor), a very e cient binary local im-age descriptor. We use AdaBoost to train our new descriptor with an unbalanced data set to address the heavily asymmetric image matching problem. To binarize our descriptor we min-imize a new similarity loss in which all weak learners share a common weight. WebSo, in 2004, D.Lowe, University of British Columbia, came up with a new algorithm, Scale Invariant Feature Transform (SIFT) in his paper, Distinctive Image Features from Scale …
