A prototype is an average of similar things. One computer-graphic manipulation we do with faces is making prototypes of different groups, such as the average university student.
|male 1||male 2||male 3||male 4||male 5||Average|
We can make prototypes of general groups, such as all men, or we can make prototypes of more specific groups, such as all the men in one family. We can even make a prototye of one person from different images of their face.
We can use the prototyping method to look at what groups of faces have in common or differ, such as seeing how an average celebrity face differs from an average student face. We can then use these pairs of prototypes to transform other faces on those dimensions.
