The pre-built demonstration highlights the capabilities of the package. Several images are put through the pre-built cutout model to deliver the cutout.

U2Net is a Python library for static image background removal
(cutout). This MLHub package is based on u2net as the backbone 
network. The pretrained model for u2net will be downloaded as
required.

See https://arxiv.org/pdf/2005.09007.pdf for a paper describing
the pre-built model and https://github.com/xuebinqin/U-2-Net
for details.

For this demo we will randomly choose an image from which to 
generate a cutout and then display the original and the cutout.

The first two examples illustrate the default cutout and the third
utilises alpha matting to obtain the cutout.
