Which process is used to confirm if two images of a face belong to the same person?

1. Identification

2. Verification

3. Recognition

4. Classification

The correct answer is: Verification

The process used to confirm if two images of a face belong to the same person is verification. Verification in face recognition systems is specifically designed to determine if two inputs (in this case, images of faces) represent the same individual. This process typically involves comparing the features extracted from both images and establishing whether they match to a certain threshold of similarity. The primary goal of verification is to answer the binary question: "Are these two images of the same person?" This involves utilizing algorithms that analyze the structural features of the face, such as distances between various facial landmarks and overall geometry. If the algorithm determines that the features of the two images are similar enough, it confirms that they belong to the same person. In contrast, identification involves determining the identity of a person from a database of known individuals, which is a broader task than simply confirming if two images are of the same face. Recognition typically refers to the overall ability of a system to understand and recognize faces in general, and classification usually relates to categorizing different types of data or information. These processes serve different purposes and are not suited for the specific task of matching two images for verification.
