前言
前几天小编在抖音上刷到一个慢慢变老的视频,播放量居然有 30W+,当时就在想这视频 Python 可不可以做?经过一番搜索,小编找到了
腾讯云的人脸年龄变化 API,上面介绍说只要用户上传一张人脸图片,基于人脸编辑与生成算法,就可以输出一张人脸变老或变年轻的图
片,并支持实现人脸不同年龄的变化。
获取 API 秘钥
第一步,在注册账号之后,打开 API 密钥管理页面(https://console.cloud.tencent.com/cam/capi)获取到 SecretId 和 SecretKey。
第二步,安装腾讯云的 SDK
pip3 install tencentcloud-sdk-python
在人脸年龄变化 API 中有一个 AgeInfo 参数,它包含了 Age 和 FaceRect 两个属性,其中 FaceRect 属性必须填人脸在照片中基于左上角的
X、Y 坐标和人脸的高度与宽度。所以先要调用人脸检测与分析 API 得到这些数据。
下面的示例图是在百度图片中截取的。

{"X": 62, "Y": 13, "Width": 145, "Height": 230} {"X": 426, "Y": 113, "Width": 115, "Height": 139}
在上面已经得到了各个人脸的 X、Y、Width、Height 属性,加上变老的年龄 Age,就可以请求年龄变化 API 了。
这里需要注意的是 models 模块,人脸检测 models 模块是在 tencentcloud.iai.v20200303 包下,人脸年龄变化的 models 是在
tencentcloud.ft.v20200304 下,两个 models 模块并不兼容。
import json from tencentcloud.common import credential from tencentcloud.common.profile.client_profile import ClientProfile from tencentcloud.common.profile.http_profile import HttpProfile from tencentcloud.common.exception.tencent_cloud_sdk_exception import TencentCloudSDKException from tencentcloud.ft.v20200304 import ft_client, models cred = credential.Credential(sid, skey) httpProfile = HttpProfile() httpProfile.endpoint = "ft.tencentcloudapi.com" clientProfile.httpProfile = httpProfile client = ft_client.FtClient(cred, "ap-beijing", clientProfile) req = models.ChangeAgePicRequest() for age in range(70, 80): params = { "Image": base64_data.decode(), "AgeInfos": [ { "Age": age, "FaceRect": { "Y": faceDetailInfos[0].FaceRect.Y, "X": faceDetailInfos[0].FaceRect.X, "Width": faceDetailInfos[0].FaceRect.Width, "Height": faceDetailInfos[0].FaceRect.Height } }, { "Age": age, "FaceRect": { "Y": faceDetailInfos[1].FaceRect.Y, "X": faceDetailInfos[1].FaceRect.X, "Width": faceDetailInfos[1].FaceRect.Width, "Height": faceDetailInfos[1].FaceRect.Height } } ], "RspImgType": "base64" } req.from_json_string(json.dumps(params)) resp = client.ChangeAgePic(req) image_base64 = resp.ResultImage image_data = base64.b64decode(image_base64) file_path = '/Users/imeng/Downloads/face/{}.png'.format(age) with open(file_path, 'wb') as f: f.write(image_data) time.sleep(1)
示例结果
最后的视频可以将图片一张一张插入 PPT 幻灯片,点击保存为视频。呀!到这里就结束了,关注我看更多教程。今天的文章到这里就结束
