Face Acquisitions a process of localizing and extracting the face region from the background. The Viola-Jones algorithm, 2001, was designed for frontal faces. is a widely used mechanism for facial detection.
The Viola and Jones algorithm uses Haar-like features to detect faces.
Given an image, the algorithm looks at many smaller sub-regions and tries to find a face by looking for specific features in each sub-region. It needs to check many different positions and scales because an image can contain many faces of various sizes. |
