Details:

As discussed in this OpenCV page
<https://docs.opencv.org/3.4/d3/dc1/tutorial_basic_linear_transform.html>,
there are some basic operators in image processing that can greatly help in
enhancing the features of a color image: "contrast", "brightness" and "gamma".


We should thus immplementing them as options in ConvertType to help users
improve their output color images.
