OpenCV conventions

The RBG color model standard for OpenCV is: Blue, Green, Red (in that order).
In OpenCV the X is positive from left ro right, but Y is from top to bottom. So the origin of the images is the upper left corner.
The image as matrix is [y, x]
In OpenCV HSL have the following values:
- Hue [0, 180]
- Saturation [0, 255]
- Value [0, 255]
