Detect 2D & 3D Facial Landmarks in Pictures via Python
The Open source Python Library Face-Alignment has included a very powerful feature for detecting 2D & 3D facial landmarks in pictures inside Python applications. Face-Alignment employs Convolutional Neural Networks (CNNs) to detect and localize facial landmarks. It offers pre-trained models that are capable of identifying a set of key facial landmarks, typically including eyes, eyebrows, nose, mouth, and jawline. To achieve the goal first you need to read the image file using OpenCV's imread() function. The following examples shows how to detect 2D and 3D facial landmarks inside pictures using Python code.
Detect 2D Facial Landmarks in Pictures via Python API
import face_alignment from skimage import io fa = face_alignment.FaceAlignment(face_alignment.LandmarksType.TWO_D, flip_input=False) input = io.imread('../test/assets/aflw-test.jpg') preds = fa.get_landmarks(input)
Detect 3D Facial Landmarks in Pictures via Python API
import face_alignment from skimage import io fa = face_alignment.FaceAlignment(face_alignment.LandmarksType.THREE_D, flip_input=False) input = io.imread('../test/assets/aflw-test.jpg') preds = fa.get_landmarks(input)
Multiple Face Detection inside Python Apps
TThe Face-Alignment library has included support for detecting multiple faces using Python API with ease. The library supports the detection and alignment of multiple faces in an image simultaneously without any external dependencies. This feature proves useful in applications where multiple faces need to be processed concurrently thus making it suitable for applications involving group photos or videos with multiple individuals. With its state-of-the-art algorithms, pre-trained models, and modular framework, it simplifies the process of facial landmark localization.
