Title:
IMAGE ANALYSIS DEVICE, IMAGE ANALYSIS METHOD, AND COMPUTER-READABLE RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/123748
Kind Code:
A1
Abstract:
Provided are an image analysis device, and so on, that enable easy association between a synthetic aperture radar (SAR) image and an object. This image analysis device is provided with: a stable reflection point identification unit for identifying, on the basis of a plurality of SAR images, stable reflection points at which reflection is stable in those SAR images; a phase identification unit for identifying the phase at each of the stable reflection points on the basis of the SAR images and the locations of stable reflection points in those SAR images; and a clustering means for clustering stable reflection points on the basis of Euclidean distances between the stable reflection points and phase correlations between the stable reflection points.
