Research Paper Overview
PeftCD: Leveraging Vision Foundation Models with Parameter-Efficient Fine-Tuning for Remote Sensing Change Detection
Summary
PeftCD is a remote sensing change detection framework that addresses pseudo changes, limited labeled data, and cross-domain generalization by integrating Parameter-Efficient Fine-Tuning (PEFT) techniques into Vision Foundation Models (VFMs). It uses a weight-sharing Siamese encoder with LoRA and Adapter modules for efficient adaptation, leveraging backbones like SAM2 and DINOv3. A lightweight decoder complements the design, achieving state-of-the-art results on multiple public datasets with precise boundaries and strong pseudo-change suppression.
