Video Image Tracing Based on Improved SIFT Feature Matching Algorithm
In this paper, we focus on the extraction problem of the target motion trajectory and make deep research. For Euclidean distance of SIFT feature matching algorithm is not adaptively adjustable, a improved SIFT feature matching algorithm based on multi-objective optimization is proposed. The optimization model is established to reduce mismatch rate, which consider Euclidean distance between corr...
متن کاملAutomated Photogrammetric Image Matching with Sift Algorithm and Delaunay Triangulation
An algorithm for image matching of multi-sensor and multi-temporal satellite images is developed. The method is based on the SIFT feature detector proposed by Lowe in (Lowe, 1999). First, SIFT feature points are detected independently in two images (reference and sensed image). The features detected are invariant to image rotations, translations, scaling and also to changes in illumination, bri...
متن کاملApplying SIFT Descriptors to Stellar Image Matching
Stellar image matching allows to verify if a given pair of images belongs to the same stellar object/area, or knowing that they correspond to the same sky area, to verify if there are some changes between them due to an stellar event (supernova event, changes in the object position, etc). Some applications are stellar photometry, telescope tracking and pointing, robot telescopes, and sky monito...
متن کاملRobust Image Matching with Selected SIFT Descriptors
A robust image matching algorithm using a set of selected SIFT descriptors is investigated in this work. We first utilize the colorbased segmentation method and the watershed algorithm to separate foreground and background regions in images and then search the corresponding SIFT descriptors along foreground contours. These selected SIFT descriptors can offer more robust and stable image matchin...
متن کاملImage Matching Optimizing Approach Based on SIFT ⋆
In this paper we introduced an improved SIFT algorithm, which is used to embedded computer vision system. In order to reduce time cost and improve correct match rate, we replaced Gaussian filter with box filter to produce scale-space and used 3D quadratic instead of pixel differences in computing Hessian and gradient. We used second derivative to compute magnitude and orientation of interest po...
