Sparse Constrained Adaptive Structure Consistency based Unsupervised Image Regression for Heterogeneous Remote Sensing Change Detection

Code: SCASC - 2021 This is a test program for the Sparse Constrained Adaptive Structure Consistency based method (SCASC) for heterogeneous change detection.

SCASC is an unsupervised image regression method based on the structure consistency between heterogeneous images. SCASC first adaptively constructs a similarity graph to represent the structure of pre-event image, then uses the graph to translate the pre-event image to the domain of post-event image, and then computes the difference image. Finally, a superpixel-based Markovian segmentation model is designed to segment the difference image into changed and unchanged classes.

In this work, due to the computational complexity, we only consider the forward transformation, i.e., translating the pre-event image to the domain of post-event image. Our future work is to improve its computation efficiency and design an effective fusion strategy to fuse the forward and backward detection results, thus improving the detection performance.

Other codes will be updated soon.
