Abstract: In this study, we introduce a refined algorithm for the fine InSAR image coregistration which could be used in highly decorrelated scenes. The refinement is introduced at the point of selection of points necessary for the estimation of the offset vectors between master and slave image. A new approach for point selection based on the Harris corner detector algorithm is presented. The new point selection algorithm results with the clusters of point candidates for the offset vectors over a scene. Consequently, the number of points and their spatial distribution are improved, which results in a better global quality of the coregistration model

Impact of DEM-Assisted Coregistration on High-Resolution SAR Interferometry
TL;DR: An improved elevation-assisted image-coregistration procedure can be adopted to provide better prediction of the offset vectors and the impact of the finite vertical accuracy of the DEM on the final coregistration precision for different resolutions and baselines is evaluated.
MST-based stepwise connection strategies for multipass Radar data, with application to coregistration and equalization
TL;DR: Results show an improvement in the quality of the stepwise (SW)-processed image stack with respect to the classical single-master procedure, confirming that the SW approach is able to provide better conditions for the estimation of correlation-related InSAR parameters.

An InSAR Fine Registration Algorithm Using Uniform Tie Points Based on Voronoi Diagram
TL;DR: A new InSAR coregistration method is proposed, which considers both the coherence of the reference points and their topographical distribution, and improves the accuracy of geometrical mapping functions and overcomes the limitation of the conventional registration method when the references points locate in low coherent area.

A Computational Approach to Edge Detection
TL;DR: There is a natural uncertainty principle between detection and localization performance, which are the two main goals, and with this principle a single operator shape is derived which is optimal at any scale.

- 01 Jan 1988
TL;DR: The problem the authors are addressing in Alvey Project MMI149 is that of using computer vision to understand the unconstrained 3D world, in which the viewed scenes will in general contain too wide a diversity of objects for topdown recognition techniques to work.
A survey of image registration techniques
TL;DR: This paper organizes this material by establishing the relationship between the variations in the images and the type of registration techniques which can most appropriately be applied, and establishing a framework for understanding the merits and relationships between the wide variety of existing techniques.

TL;DR: In this article, the Permanent Scatterers (PS) were used as a "natural GPS network" to monitor terrain motion, analysing the phase history of each one, and results obtained using 34 ERS SAR images gathered over the Italian city of Ancona are presented.
