.. currentmodule:: ctapipe.image

`ctapipe.image` contains all algorithms that operate on Cherenkov camera images.

A *Cherenkov image* is defined as two pieces of data:

* a `numpy` array of pixel values (which can either be 1D, or 2D if time samples are included)
* a description of the Camera geometry (pixel positions, etc), usually a `ctapipe.instrument.CameraGeometry` object


This module contains the following sub-modules, but the most important functions of each are imported into the `ctapipe.image` namespace
