Classical feature descriptors, such as SIFT, SURF, etc., are usually compared and matched using the Euclidean distance (or L2-norm). Other techniques for matching these features are Cosine similarity, ...

WebNov 25, 2016 · I have previously worked with SIFT, libsiftfast, Bundler, PMVS2, and CMVS, and have achieved some very good results with these tools. I have come across some examples where Photoscan outperforms Bundler when it comes to calculating camera position, orientation, and distortion parameters, especially when the focal length is … WebFinally, the SIFT algorithm normalizes the feature descriptor for rotation. It finds the dominant gradient direction in the patch around the key point and shfits the gradient histograms such that the first orientation bin corresponds to that direction. This makes the descriptors invariant to in-plane rotation.
