Face Embeddings using Deepface

Author: Krishna katyal

Description

The pipeline is used to extract the feature vector of detected faces in images. It uses the for face embeddings Deepface.

Code Example

Load an image from path './test_face'.

Write the pipeline in simplified style:

import towhee 
towhee.glob('./test_face.jpg') \
  .image_decode.cv2() \
  .face_embedding.deepface(model_name = 'DeepFace').tolist()

Write a pipeline with explicit inputs/outputs name specifications:

import towhee

towhee.glob['path']('./test_face.jpgg') \
  .image_decode.cv2['path', 'img']() \
  .face_embedding.deepface['img', 'vec']() \
  .select['img','vec']() \
  .show()

Factory Constructor

Create the operator via the following factory method

face_embedding.deepface(model_name = 'which model to use')

Model options:

• VGG-Face
• FaceNet
• OpenFace
• DeepFace
• ArcFace
• Dlib
• DeepID

Interface

A face embedding operator takes a face image as input. It extracts the embedding in ndarray.

Parameters:

​ img: towhee.types.Image (a sub-class of numpy.ndarray)

​ The input image.

Returns: numpy.ndarray

​ The extracted image embedding.
