Change Detection

276 papers with code • 14 benchmarks • 14 datasets

Change Detection is a computer vision task that involves detecting changes in an image or video sequence over time. The goal is to identify areas in the image or video that have undergone changes, such as appearance changes, object disappearance or appearance, or even changes in the scene's background.

SNUNet-CD: A Densely Connected Siamese Network for Change Detection of VHR Images

likyoo/Siam-NestedUNet 17 Feb 2021

Recent change detection methods always focus on the extraction of deep change semantic feature, but ignore the importance of shallow-layer information containing high-resolution and fine-grained features, this often leads to the uncertainty of the pixels at the edge of the changed target and the determination miss of small targets.

Remote Sensing Image Change Detection with Transformers
