Face Landmark and Pose with the Face Module

Face landmark detection is the process of finding points of interest in an image of a human face. It recently saw a spur of interest in the computer vision community, as it has many compelling applications; for example, detecting emotion through facial gestures, estimating gaze direction, changing facial appearance (face swap), augmenting faces with graphics, and puppeteering of virtual characters. We can see many of these applications in today's smartphones and PC web-camera programs. To achieve these applications, the landmark detector must find dozens of points on the face, such as corners of the mouth, corners of eyes, the silhouette of the jaws, and many more. To that end, many algorithms were ...
