Title
Constrained Symmetry for Change Detection
Abstract
The automation of imagery analysis processes leads to the need to detect change between pairs of aerial reconnaissance images. Ap- proximate camera models are available for these images, accurate up to a translation, and these are augmented with further constraints relat- ing to the task of monitoring vehicles. Horizontal, bilateral, Euclidean symmetry is used as a generic object model by which segmented curves are grouped, first in a 2-d approximation, and then in 3-d, resulting in a sparse 3-d Euclidean reconstruction of a symmetric object from a single view. The method is applied to sample images of parked aircraft.
