The LEVIR-CC dataset contains 10,077 pairs of bi-temporal remote sensing images and 50,385 sentences describing the differences between images. dataset_example Some examples of our dataset are as follows:

LEVIR- MCI Dataset

The dataset contains bi-temporal images as well as diverse change detection masks and descriptive sentences. It provides a crucial data foundation for exploring multi-task learning for change detection and change captioning.
