Dataset Card for JL1-CD

Dataset Description (English)

Overview

JL1-CD is a large-scale, sub-meter, all-inclusive open-source dataset for remote sensing image change detection (CD). It contains 5,000 pairs of 512×512 pixel satellite images with a resolution of 0.5 to 0.75 meters, covering various types of surface changes in multiple regions of China. JL1-CD includes not only common human-induced changes (e.g., buildings, roads) but also natural changes (e.g., forests, water bodies, grasslands). The dataset aims to provide a comprehensive benchmark for change detection algorithms.

Dataset Structure

• Number of Image Pairs: 5,000 pairs
• Image Size: 512×512 pixels
• Resolution: 0.5 to 0.75 meters
• Change Types: Human-induced changes (e.g., buildings, roads) and natural changes (e.g., forests, water bodies, grasslands)
• Dataset Split: 4,000 pairs for training, 1,000 pairs for testing

Dataset Features

• High Resolution: Provides rich spatial information, facilitating visual interpretation.
• Comprehensive: Covers various change types, enhancing the generalization capability of algorithms.
• Open Source: The dataset is fully open-source, supporting the research community's use and improvement.

Usage

The JL1-CD dataset can be used to train and evaluate remote sensing image change detection models. The image pairs in the dataset include images from two time points along with corresponding pixel-level change labels. Users can utilize this dataset to develop, test, and optimize change detection algorithms.

Benchmark Results

The Multi-Teacher Knowledge Distillation (MTKD) framework proposed in the paper achieves new state-of-the-art (SOTA) results on the JL1-CD dataset. Experiments demonstrate that the MTKD framework significantly improves the performance of change detection models with various network architectures and parameter sizes.
