Inception-ResNet v1 Face Embedding Operator

author: David Wang

Description

This operator extracts embedding vector from facial image using Inception-ResNet. The implementation is an adaptation from timesler/facenet-pytorch.

Code Example

Extract face image embedding from './img.png'.

Write a pipeline with explicit inputs/outputs name specifications:

from towhee import pipe, ops, DataCollection

p = (
    pipe.input('path')
        .map('path', 'img', ops.image_decode())
        .map('img', 'vec', ops.face_embedding.inceptionresnetv1())
        .output('img', 'vec')
)

DataCollection(p('img.png')).show()

Factory Constructor

Create the operator via the following factory method:

face_embedding.inceptionresnetv1(image_size = 160)

Parameters:

image_size: int

Scaled input image size to extract embedding. The higher resolution would generate the more discriminative feature but cost more time to calculate.

supported types: int, default is 160.

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.
