Unit testing #16
Description
As each of the filters are separate, they should be fairly easy to test.
- Face Highlighter test needs to return correct position when fed an image
- Eye Highlighter test needs to return correct position when fed an image
- Recolour needs to work
- Landmarks needs to work
- Enrolment needs to save images in the correct directory
It would also be useful to have a pre-filter to draw test images on the frame
