cloud and cloud shadow detection
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.
Is that original image?
there is the cloud mask (red) and the cloud shadow mask (blue) obtained by applying the thresholds on the image behind (band)
Actually, I can't help it.
