      Description

      For the deblender to be optimal in the long term survey, which includes possibly deblending entire images as a single blend, we need to be able to define a bounding box for each source that is a small fraction of the total image size (see the issue created by Peter Melchior
      at https://github.com/fred3m/deblender/issues/14).

      Issue DM-11718 has been created to develop an effective algorithm to do this, but will not likely be added to the stack until after testing has been run on a large patch of real HSC images.

      This ticket is created to track work that has already been done to test whether or not such an algorithm might be possible, and resulted in this ipython notebook, which shows that such a procedure is likely to exist.

      It also shows the possibility of performing multi-band object detection in the future, although discussion with Peter Melchior indicate that this might be difficult (and/or time consuming) in practice.
