Tiled image processing
Tiled image processing#
If image data is too large to fit into memory, it becomes necessary to split the image into multiple tiles and process them individually. While this is step is straightforward, it can become very challenging to stitch the resulting image tiles together and return one big result image. In this section we will elaborate on multiple strategies to deal with tiled image processing. The dask library enables processing tiled images easy to use. This chapter starts with a complete workflow showing dask in action and then explains the individual steps for setting up a proper workflow for processing your data afterwards.
