I'm working on a machine vision project and work with a sequence of recorded stock images to test my algorithms with. They are city images that were recorded in relatively good weather conditions. Now I would like to be able to simulate some alternative weather conditions using these same pictures. I'm thinking of rain, fog, maybe even snow.
I was wondering if I could apply a filter as it is explained on https://www.lifewire.com/produce-fake-rain-in-gimp-1701711 to 1000s of the stock images I'm using?
