嗨嗨,大家好呀 ,我是小圆。有时候我们的证件照需要换底色,又来不及去照相馆拍照,用ps也不好抠图,所以今天给你们分享一下如何用python来抠图,并换底色

创建应用
里面的需要填写的内容可以随便写,新用户要去领取免费资源,不然使用不了。
创建完成在应用列表记录 API Key、Secret Key的值 ,稍后要用。
至此,注册账号和创建应用的任务就完成了。
import os
import requests
import base64
import cv2
import numpy as np
from PIL import Image
from pathlib import Path
path = os.getcwd()
paths = list(Path(path).glob('*'))
def get_access_token():
url = 'https://aip.baidubce.com/oauth/2.0/token'
data = {
'grant_type': 'client_credentials', # 固定值
'client_id': '替换成你的API Key', # 在开放平台注册后所建应用的API Key
'client_secret': '替换成你的Secret Key' # 所建应用的Secret Key
}
res = requests.post(url, data=data)
res = res.json()
access_token = res['access_token']
return access_token

1. 该程序会覆盖原文件,使用前请备份文件,以免造成数据丢失
2. 将程序复制到和待处理的照片同目录下,双击程序即可运行

代码不算难,就是中途有许多小问题,比如图片大小不能超过4MB,就得压缩照片,路径之类的问题,总之实现了这个功能很开心!
好啦,今天的分享到这里就结束了 ~
