The scale-invariant feature transform (SIFT) is a computer vision algorithm to detect, describe, and match local features in images, invented by David Lowe in 1999. Applications include object recognition, robotic mapping and navigation, image stitching, 3D modeling, gesture recognition, video tracking, individual identification of wildlife and match moving. SIFT keypoints of objects are first extracted from a set of reference images and stored in a data… WebThe algorithm based on SIFT feature matching and Kalman filter has been used for digital video stabilization, it is efficient in many applications. However, video obtained by the method is still not stable. An improved scheme in motion filtering is proposed in this paper. The scheme is that global motion vector estimated by Kalman filter is filtered by an ideal …
