The performance of image matching by SIFT descriptors can be improved in the sense of achieving higher efficiency scores and lower 1-precision scores by replacing the scale-space extrema of the difference-of-Gaussians operator in original SIFT by scale-space extrema of the determinant of the Hessian, or more generally considering a more general ...
The standard version of SURF is several times faster than SIFT and claimed by its authors to be more robust against different image transformations than SIFT. To detect interest points, SURF uses an integer approximation of the determinant of Hessian blob detector , which can be computed with 3 integer operations using a precomputed integral ...
Oriented FAST and rotated BRIEF (ORB) is a fast robust local feature detector, first presented by Ethan Rublee et al. in 2011, [1] that can be used in computer vision tasks like object recognition or 3D reconstruction.
Rank SIFT algorithm is the revised SIFT (Scale-invariant feature transform) algorithm which uses ranking techniques to improve the performance of the SIFT algorithm.In fact, ranking techniques can be used in key point localization or descriptor generation of the original SIFT algorithm.
Renters insurance. Even if you don’t own your home, it’s worth it to invest in renters insurance that can cover you, your valuables and your living expenses against damage, theft and other loss.
Following a traditional inaugural prayer service at Washington National Cathedral on Tuesday, during which an Episcopal bishop called on President Donald Trump to show "mercy" toward LGBTQ people ...

In (Lindeberg 2013b, 2015) [2] [3] it is shown that the determinant of the Hessian operator performs significantly better than the Laplacian operator or its difference-of-Gaussians approximation, as well as better than the Harris or Harris-Laplace operators, for image-based matching using local SIFT-like or SURF-like image descriptors, leading ...
