"image" is the Torch7 distribution package for processing images. It contains a wide variety of functions divided into the following categories:

* Saving and loading images as JPEG, PNG, PPM and PGM;
* Simple transformations like translation, scaling and rotation;
* Parameterized transformations like convolutions and warping;
* Simple Drawing Routines like drawing text or a rectangle on an image;
* Graphical user interfaces like display and window;
* Color Space Conversions from and to RGB, YUV, Lab, and HSL;
* Tensor Constructors for creating Lenna, Fabio and Gaussian and
Laplacian kernels;
Note that unless specified otherwise, this package deals with images of size `nChannel x height x width`.
