Some edge cases
I'm thinking about a few edge cases and I'm interested in your insights.
Would this detect the movement correctly in case the whole scene gets suddenly saturated?
The next is a rain. In case of a weak rain some simple filtering could work - either blur or median. But what about a heavy rain? Would it detect movement all over the image?
If the image gets saturated, then my guess is it would think there was movement everywhere. But this would depend on the level. You'd have to try it.
For rain, it will also depend on what size you choose for the thumbnail dimensions. The larger the size, the better chance it will accidentally notice the rain. With smaller thumbnails, then chances are it will skip any rain once the image has been resized.
Blur is normally not necessary, since the library only works with very small thumbnail images. But again, try it and let us know if/when it helps.
