I am working on a project in Python that implies manipulating images that are pretty huge (can go up to 1.5GB).

Since filtering operations are generally local, I do not need to load the entire image to detect small objects in the images for instance. Therefore, I guess one possible solution would be to load a small patch in the image, process it, consider the next patch, and so on...

However, I believe I am not the first one to be facing this problem, and some sort of lazy library has probably been developed already. Does anybody have a pointer?

Thanks in advance
