Code could use some refactoring

[ConnorJWalker]

• Colour detection lambda is being called multiple times in multiplemethods so should probably become a private method in the detector class

• In detectIfCardUp (line 94) we are checking to see the result of a bool expression and returning true if true and false if false. Could change this to just return the bool expression, i.e return whitePrecentage > notWhitePercentage

• Might be an idea to remove some of the less helpful windows like canny and greyscale? Not sure if we need these. Or we could add these as option through command line arguments? Not really sure
