This utility takes an image or an array of images and loads them to a matrix. You can optionally specify the height '--height (-H)' width '--width (-w)' and channel '--channels (-c)' of the images that needs to be loaded; otherwise, these parameters will be automatically detected from the image. There are other options too, that can be specified such as '--quality (-q)'.

You can also provide a dataset and save them as images using '--dataset_file (-I)' and '--save (-s)' as an parameter.
