Question

question 10 of 10
how might a computer programmer write an algorithm that identifies a
persons face?

a. by using numerous measurements of facial features to create a
mathematical faceprint

b. by sketching outlines of peoples facial features to be loaded into
the computer

c. by accessing and inputting genetic data for all the types of faces
they want to identify

d. by asking thousands of people to describe the looks of people
theyve seen

Explanation:

To determine the correct answer, we analyze each option:

• Option A: Facial recognition algorithms typically use measurements of facial features (like distances between eyes, nose shape, etc.) to create a mathematical representation (faceprint) for identification. This is a common and accurate method in computer programming for face identification.
• Option B: Sketching outlines is not a practical or standard method for computer - based face identification as it is difficult to convert sketches into a format that a computer can use for accurate identification at scale.
• Option C: Accessing genetic data is not a typical method for face identification in programming. Genetic data is complex and not directly related to the visual features used for face recognition, and also raises significant privacy and ethical issues.
• Option D: Asking people to describe faces is subjective and inconsistent, and it would be extremely difficult to use these descriptions for a computer algorithm to accurately identify faces.

Answer:

A. By using numerous measurements of facial features to create a mathematical faceprint
