One of the things that you can do with OpenVINO is to add colour to a greyscale image. For example, you could turn this greyscale image of an elephant into a colour one:

It supports fully automatic and also user-guided image colourisation by using two different types of pre-trained models. This means that you could have an application that allows the user to fine-tune the end result by simply clicking and selecting the colours they want to be included in the colourised image.

If you would like to know more about how to do this, and other amazing applications of OpenVINO, specially about Deep Learning in Computer Vision, with source code and explanations, make sure to sign up here. I will be sending more information about this project to the people in my list first, before anyone else.
