Description

technical field [0001] The invention relates to the field of image processing, in particular to an optical remote sensing image target area detection device and method. Background technique [0002] The research objects of target area detection in optical remote sensing images mainly include synthetic aperture radar (SAR) images and optical satellite optical remote sensing images. Among them, SAR images have low resolution and high noise, while optical remote sensing images have high spatial resolution, intuitive imaging, rich content, clear target structure, and have advantages that SAR images do not have in target area detection. Therefore, optical remote sensing Image has become a research hotspot in remote sensing image target area detection in recent years. [0003] In the prior art, the target area of ​​the optical remote sensing image is mainly detected by the threshold segmentation method. The threshold segmentation method uses the difference between the gray value...
