Matlab code for detecting Affine spatial interest points. Includes Harris, Laplacian, det(Hessian) and Ridge interest point operators in combination with spatial scale selection based on the extrema of scale-normalized Laplacian and affine adaptation basen on second-moment matrix. Scale and shape adaptation are optional and disjoint. Zip archive: affintpoints.zip Ref: An affine invariant interest point detector , K.Mikolajczyk and C.Schmid, ECCV 02, pp.I:128-142. What is in the package: 1) ineterst point detection of different kinds (Harris, Laplace, det(H), Ridge) 2) scale, shape and position adaptation procedure 3) demo examples and a script for batch-mode computation and saving of the results what is not in the package: - no rotation estimation - no region descriptor computation
