Description

technical field [0001] The invention belongs to the technical field of image processing, and relates to a remote sensing image change detection method, in particular to a remote sensing image change detection method based on neural network structure search, which can be used in the fields of geological disaster monitoring, land cover investigation, urban planning and the like. Background technique [0002] Remote sensing images are images obtained by collecting and processing the electromagnetic radiation energy of ground objects and targets by remote sensing imaging instruments on the remote sensing platform. The two remote sensing images obtained by shooting the same place at two different times can reflect the changes of ground objects. Remote sensing image change detection refers to the detection of areas that have changed between two remote sensing images taken at different times in the same place. How to improve the accuracy of change detection is the focus and diffic...
