Can i know what are all the face recognitions the dlib has to offer us. This is in the case of face landmarks.
There are many landmark detectors dlib has to offer us. Mostly, The first one is: 68-point landmark detectors: This pre-trained landmark detector identifies 68 points ((x,y) coordinates) in a human face. These points localize the region around the eyes, eyebrows, nose, mouth, chin and jaw. The second one is:5 point landmark detector: To make things faster than the 68 point detector, dlib introduced the 5 point detector which assigns 2 points for the corners of the left eye, 2 points for the right eye and one point for the nose. This detector is most commonly used for alignment of faces. There is a good article in gfg:Link There is also another link : good explanation with examples.
