By default, squidpy.im.process processes the entire input image at once. In the case of high-resolution tissue slides however, the images might be too big to fit in memory and cannot be processed at once. In that case you can use the argument chunks to tile the image in crops of shape chunks, process each crop, and re-assemble the resulting image.
