Sample Question 1
What is the primary difference between face detection and face recognition?

Detection locates faces; recognition identifies specific individuals

Detection identifies people; recognition only finds face locations

Detection uses neural networks; recognition uses traditional algorithms

Detection is faster; recognition is always more accurate

Sample Question 2
Which algorithm is commonly used for face detection in modern applications?

Viola-Jones cascade classifier

K-means clustering

Principal Component Analysis (PCA)

Naive Bayes classifier

Sample Question 3
Which metric measures the percentage of correctly identified individuals in a face recognition system?

Precision and recall

False Positive Rate (FPR)

True Positive Rate (TPR)

All of the above
