Custom MATLAB-Based Correlation Framework for Optical Image Displacement Mapping

Le résumé fourni par la source

This repository contains a custom MATLAB-based image correlation framework developed to quantify coseismic surface displacements from optical imagery. The algorithm is inspired by the principles of COSI-Corr but is fully implemented by the authors, allowing fine control over correlation parameters, filtering strategies, and geospatial transformations. The framework is optimized for large-format orthorectified aerial photographs and high-resolution satellite imagery (e.g., SPOT-6). The code implements a normalized cross-correlation approach using moving template windows, multi-stage quality filtering, and directional selection consistent with left-lateral strike-slip fault kinematics. The implementation was developed to ensure transparency, reproducibility, and robustness under complex surface conditions. This software accompanies a scientific manuscript currently under journal review.
