How can I check keypoint localization step in SIFT works

WebThe author of SIFT recommends generating two such extrema images. So, you need exactly 4 DoG images. To generate 4 DoG images, you need 5 Gaussian blurred images. Hence the 5 level of blurs in each octave. In the image, I've shown just one octave. This is done for all octaves. Also, this image just shows the first part of keypoint detection. WebJan 30, 2013 · Keypoint Localization. The detected local extrema are good candidates for keypoints.However, they need to be exactly localized by fitting a 3D quadratic function to thescale-space local sample point. The quadratic function is computed using a secondorder Taylor expansion having the origin at the sample point. simple soy chicken
