Detailed Description

Graphical demo of defuzzifying and unary operations (complement, alpha-cut, truncate, scale) on membership functions.

• needs gapi interface.
• User can add new points to the main function, and switch between the different defuzzyfication methods using SPACE key.
• keys A/Z increment/decrement the threshold for alpha-cut / truncate.
• SPACE key cycles through defuzzyfying methods.
• 'x' key cycles through unary functions (complement, alpha-cut, truncate)
• 'd' key deletes the selected point
• 'a'/'z' increments/decrements the threshold for alpha-cut and truncate.
