This article introduces how to achieve a face-changing function in Python. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.

Function realization

To realize the face-changing function, we can be roughly divided into two types: one is that all the functions are realized by our own coding, and the other is realized with the help of a third-party API. The first way may require us to carry out a lot of coding, while the second way we only need a small amount of coding to achieve.

In this article, we use a simpler second way to implement this. The API interface we use is provided by Face++,. First of all, we need to register an account on the website with the registered address: https://console.faceplusplus.com.cn/register. After opening it, it is as follows:

We can register by mobile number and email. After registering the account, we log in to the login address https://console.faceplusplus.com.cn/login. After logging in, we will find that the website has created an application for us, as shown in the following figure:

What we need to use are the values of API Key and API Secret in the figure above. Let's take a look at the specific implementation code:

# obtain face key points

Def find_face (imgpath):

Print ("looking for.")

Http_url = "https://api-cn.faceplusplus.com/facepp/v3/detect"

Data = {"api_key": "your own api_key"

"api_secret": "your own api_secret"

"image_url": imgpath, "return_landmark": 1}

Files = {"image_file": open (imgpath, "rb")}

Response = requests.post (http_url, data=data, files=files)

Req_con = response.content.decode ('utf-8')

Req_dict = json.JSONDecoder () .decode (req_con)

This_json = simplejson.dumps (req_dict)

This_json2 = simplejson.loads (this_json)

Print (this_json2)

Faces = this_json2 ['faces']

List0 = faces [0]

Rectangle = list0 ['face_rectangle']

# print (rectangle)

Return rectangle

# face change. The size of the picture should not exceed 2m _ number to indicate the similarity of the face change.

Def merge_face (image_url1, image_url2, image_url, number):

Ff1 = find_face (image_url1)

Ff2 = find_face (image_url2)

Rectangle1 = str (str (ff1 ['top']) + "," + str (ff1 [' left']) + "," + str (ff1 ['width']) + "," + str (ff1 [' height']))

Rectangle2 = str (ff2 ['top']) + "," + str (ff2 [' left']) + "," + str (ff2 ['width']) + "," + str (ff2 [' height'])

Print (rectangle2)

Url_add = "https://api-cn.faceplusplus.com/imagepp/v1/mergeface"

F1 = open (image_url1, 'rb')

F1x64 = base64.b64encode (f1.read ())

F1.close ()

F2 = open (image_url2, 'rb')

F2room64 = base64.b64encode (f2.read ())

F2.close ()

Data = {"api_key": "your own api_key"

"api_secret": "your own api_secret"

"template_base64": F1: 64, "template_rectangle": rectangle1

"merge_base64": f2q64, "merge_rectangle": rectangle2, "merge_rate": number}

Response = requests.post (url_add, data=data)

Req_con1 = response.content.decode ('utf-8')

Req_dict = json.JSONDecoder () .decode (req_con1)

Result = req_dict ['result']

Imgdata = base64.b64decode (result)

File = open (image_url, 'wb')

File.write (imgdata)

File.close ()
