Сompare Two Faces Using Python3 Module Face_recognition?

sorry for my bad english. I am trying to compare two faces using python3 module 'face_recognition' here is an example of calculating euclidean distance in python pdist([vector1, v

Solution 1:

Here is what you need!

import json


def load(str_data):
    str_data = str_data.replace("[", "").replace("]", "")
    result = []
    for i, line in enumerate(str_data.split("\n")):
        result.append([])
        for element in line.replace("  ", " ").split(" "):
            try:
                result[i].append(float(element))
            except ValueError:
                pass
    return result


def distance(model, test):
    distance = 0
    for i, line in enumerate(model):
        dist_line = 0
        for j, element in enumerate(line):
            dist_line += (element - test[i][j]) ** 2
        distance += dist_line ** 0.5
    return distance

    print(distance(
        load(Find_me_image),
        load(New_image)
    ))

You need first to convert your datas using load function. Then calculate distance using distance function. As your datas are the sames, I modify New_image datas to test the function.
