Question 6

+2 marksOne correct option

Which of the following is the correct sequence of steps of the SIFT algorithm?
1. Using the Taylor series expansion of the scale-space function, lo-calize the key points. 2. Estimate the orientation of keypoints using the local image gra-dients.
3. Find the edge points using the eigenvalues of the Hessian and reject these points.
4. Find a raw SIFT descriptor vector using the gradient orientations of the neighborhood around the key points.
5. Detect extreme points in scale space using an approximation of the Laplacian of Gaussian.
