Abstract base class for any task that is to be used as `ImageMapReduceConfig.mapper`. Notes ----- An `ImageMapper` is responsible for processing individual sub-exposures in its `run` method, which is called from `ImageMapReduceTask.run`. `run` may return a processed new sub-exposure which can be be "stitched" back into a new resulting larger exposure (depending on the configured `ImageReducer`); otherwise if it does not return an lsst.afw.image.Exposure, then the `ImageReducer.config.reducer.reduceOperation` should be set to 'none' and the result will be propagated as-is.

lsst.ip.diffim.imageMapReduce.ImageMapper.run | ( | self, | |
subExposure, | |||

** | kwargs ) |
Perform operation on `subExposure`. To be implemented by subclasses. See class docstring for more details. This method is given the `subExposure` which is to be operated upon, and an `expandedSubExposure` which will contain `subExposure` with additional surrounding pixels. This allows for, for example, convolutions (which should be performed on `expandedSubExposure`), to prevent the returned sub-exposure from containing invalid pixels. This method may return a new, processed sub-exposure which can be be "stitched" back into a new resulting larger exposure (depending on the paired, configured `ImageReducer`); otherwise if it does not return an lsst.afw.image.Exposure, then the `ImageReducer.config.mapper.reduceOperation` should be set to 'none' and the result will be propagated as-is. Parameters ---------- subExposure : `lsst.afw.image.Exposure` the sub-exposure upon which to operate expandedSubExposure : `lsst.afw.image.Exposure` the expanded sub-exposure upon which to operate fullBBox : `lsst.geom.Box2I` the bounding box of the original exposure kwargs : additional keyword arguments propagated from `ImageMapReduceTask.run`. Returns ------- result : `lsst.pipe.base.Struct` A structure containing the result of the `subExposure` processing, which may itself be of any type. See above for details. If it is an `lsst.afw.image.Exposure` (processed sub-exposure), then the name in the Struct should be 'subExposure'. This is implemented here as a pass-through example only.
Reimplemented in lsst.ip.diffim.imageDecorrelation.DecorrelateALKernelMapper.
