menpocli provides a command line interface for performing either face alignment or face detection on folders of images. For example, to perform face detection on a folder of images:
> menpodetect ./folder_of_images
which will save a number of
PTS files containing the corners of the bounding box for each face in the image. Similarly, to perform face alignment:
> menpofit ./folder_of_images
which will use a pre-trained AAM to fit facial landmarks to the faces detected within the images.
