Selecting change image for efficient change detection

open access: yesIET Signal Processing, 2022
Change detection (CD) is a fundamental problem that aims at detecting changed objects from two observations. Previous CNN‐based CD methods detect changes through multi‐scale deep convolutional features extracted from two images.

Spectral‐spatial sequence characteristics‐based convolutional transformer for hyperspectral change detection

open access: yesCAAI Transactions on Intelligence Technology, 2023
Recently, ground coverings change detection (CD) driven by bitemporal hyperspectral images (HSIs) has become a hot topic in the remote sensing community. There are two challenges in the HSI‐CD task: (1) attribute feature representation of pixel pairs and
