How to manually update the image cache?
In my application, I call region.find() repeatedly in a loop, and the image is continuously changing.
But sometimes the find function return a location that just moved.
If I try to increase the scan rate, it is improved, but the problem is still there.
I guess maybe just because the find function is using a old image cache.
To avoid this problem, it is better to force the image cache update.
