pfla: Python Facial Landmark Analysis

A simple command line interface to automate facial analysis. pfla uses a pre-trained neural networks to detect faces and annotate them with 68 landmarks. The program also compyte four commonly used facial metrics. The output is saved to a file to allow for easy statistical analysis by the user.

Usage

usage: pfla [-h] [-d] [-l] [-m] [-o OUTPUT] [-v] path

PFLA: python facial landmark analysis. This program will read the image(s)
given as input and can apply a face detection algorithm, landmark placement
and computation of metrics. The results are returned as a text stream.

positional arguments:
  path                  path to the image or directory of images

optional arguments:
  -h, --help            show this help message and exit
  -d, --detect          detect faces and output bounding box
  -l, --landmark        annotate detected faces and output coordinates
  -m, --metrics         compute metrics and output results
  -o OUTPUT, --output OUTPUT
                        specify output filename and format/filetype of the
                        data
  -v, --verbose         increase output verbosity
