hi i'm trying to detect cloud and cloud shadow on satellite images using OpenCv (python). I can detect the clouds perfectly. I encountered a problem when detecting the cloud shadow, the problem is that in addition to detecting the cloud shadow I also detect the shadow due to the topography. is that there is a function that I can use to eliminate the shadows due to the topography with a condition (for example eliminate the shadows which are far from the clouds with a certain distance which I will choose) And thank you in advancee.

there is the cloud mask (red) and the cloud shadow mask (blue) obtained by applying the thresholds on the image behind (band)
