例句與造句

1. The determinant of the Hessian matrix is used as a measure of local change around the point and points are chosen where this determinant is maximal.
2. The maxima of the determinant of the Hessian matrix are then interpolated in scale and image space with the method proposed by Brown, et al.
3. In contrast to the Hessian-Laplacian detector by Mikolajczyk and Schmid, SURF also uses the determinant of the Hessian for selecting the scale, as is also done by Lindeberg.
4. As discussed in Mikolajczyk et al . ( 2005 ), by choosing points that maximize the determinant of the Hessian, this measure penalizes longer structures that have small second derivatives ( signal changes ) in a single direction.
5. This usually means that the point is a minimum, but the problem is that we did not even substitute x = ( 1 / 4 ) ^ ( 1 / 12 ) into the determinant of the Hessian matrix.
6. It's difficult to find determinant of the hessian in a sentence. 用determinant of the hessian造句挺難的
7. Besides the commonly used multi-scale Harris operator, this affine shape adaptation can also be applied to other types of interest point operators such as the Laplacian / Difference of Gaussian blob operator and the determinant of the Hessian ( Lindeberg 2008 ).
8. Since difference-of-Gaussians interest points constitute a numerical approximation of Laplacian of the Gaussian interest points, this shows that a substantial increase in matching performance is possible by replacing the difference-of-Gaussians interest points in SIFT by determinant of the Hessian interest points.
9. Hence, besides the commonly used multi-scale Harris operator, affine shape adaptation can be applied to other corner detectors as listed in this article as well as to differential blob detectors such as the Laplacian / difference of Gaussian operator, the determinant of the Hessian and the Hessian Laplace operator.
10. In Lindeberg ( 2015 ) such pure Gauss-SIFT image descriptors were combined with a set of generalized scale-space interest points comprising the Laplacian of the Gaussian, the determinant of the Hessian, four new unsigned or signed Hessian feature strength measures as well as Harris-Laplace and Shi-and-Tomasi interests points.
11. This study therefore shows that discregarding discretization effects the pure image descriptor in SIFT is significantly better than the pure image descriptor in SURF, whereas the underlying interest point detector in SURF, which can be seen as numerical approximation to scale-space extrema of the determinant of the Hessian, is significantly better than the underlying interest point detector is SIFT.
12. Note that for functions of three or more variables, the " determinant " of the Hessian does not provide enough information to classify the critical point, because the number of jointly sufficient second-order conditions is equal to the number of variables, and the sign condition on the determinant of the Hessian is only one of the conditions.
13. A second-order equation for the unknown function " u " of two variables " x ", " y " is of Monge Amp鑢e type if it is linear in the determinant of the Hessian matrix of " u " and in the second-order partial derivatives of " u ".
14. 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 family of generalized scale-space interest points.
