In remote sensing image processing, it is often necessary to use multiple images for scientific research. In individual cases, the coverage of multiple pieces of data is different, so when performing operations such as change detection and image fusion, it is necessary to obtain the overlapping area of the image. ENVI 扩展补丁（ get_overlapping_region.sav ），可以自动获取重叠区域影像，并且可以自定义掩膜值。 However, the operation is more complicated. The ENVI extended patch ( get_overlapping_region.sav ) can automatically obtain the image of the overlapping area, and can customize the mask value.
Patch copy path:
：将补丁拷贝至 X:\Program Files\Exelis\ENVI50\extensions 文件夹 ENVI 5 : Copy the patch to the X: \ Program Files \ Exelis \ ENVI50 \ extensions folder
：将补丁拷贝至 X:\Program Files\Exelis\ENVI50\classic\save_add 文件夹 ENVI Classic : Copy the patch to the X: \ Program Files \ Exelis \ ENVI50 \ classic \ save_add folder
及之前： C:\Program Files\ITT\IDL\IDL80\products\envi48\save_add 文件夹 ENVI 4.8 and before: C: \ Program Files \ ITT \ IDL \ IDL80 \ products \ envi48 \ save_add folder
ENVI 即可。 Note: Restart ENVI after copying .
