You can use Boolean operators in Band Math in ENVI to get intersection of all of these raster images.

Also, you can use condition tool in raster calculator in ArcGIS to perform required operation.

Note :- Required regions should be assigned same pixel value in all the datasets.

Hi Sheetal Kumari

If your threshold yields a boolean map, then you need to simply multiply the rasters using band math (b1*b2) to get intersection (AND operator). See below for details

And operator

B1 B2 Output

1 1 1

1 0 0

0 1 0

0 0 0

you can try with GIS , Geoprocessing/intersection
