Target Localization Based on Invariant Image Features

Abstract

Distinctive invariant features from images are perform reliable to image scale and rotation, also applicable to change in 3D viewpoint, so it is widely used in image matching and target locating. This paper analyses the extracting theory and process of invariant features from images in detail, and presents a method that can be used to calculate transforming modulus between two images are according to invariant features, finally accomplishing the target locating, which exist in two images together. Simulation results indicate that the paper method have excellent performance in target locating, it is precision for target locating between two images based on invariant features from images.
