本文档为您介绍视频人像分割能力常用语言和常见情况的示例代码。

说明

  • 您可以进入在线咨询获取在线人工帮助。

  • 阿里云视觉智能开放平台视觉AI能力API接入、接口使用或问题咨询等，请通过钉钉群（23109592）加入阿里云视觉智能开放平台咨询群联系我们。

能力介绍

关于视频人像分割能力的功能介绍以及具体调用参数说明，请参见视频人像分割。

SDK包安装

常见语言的SDK依赖包信息，请参见SDK总览。

配置环境变量

配置环境变量ALIBABA_CLOUD_ACCESS_KEY_ID和ALIBABA_CLOUD_ACCESS_KEY_SECRET。

重要

  • 阿里云账号AccessKey拥有所有API的访问权限，建议您使用RAM用户进行API访问或日常运维，具体操作，请参见创建RAM用户。

  • 请不要将AccessKey ID和AccessKey Secret保存到工程代码里，否则可能导致AccessKey泄露，威胁您账号下所有资源的安全。

  • Linux和macOS系统配置方法

    1. 在IntelliJ IDEA中打开终端Terminal。

    2. 执行以下命令，配置环境变量。

      <access_key_id>需替换为您RAM用户的AccessKey ID，<access_key_secret>替换为您RAM用户的AccessKey Secret。如果后续需要进行更多权限相关的配置，具体操作请参见使用RAM Policy控制访问权限。

      export ALIBABA_CLOUD_ACCESS_KEY_ID=<access_key_id> 
export ALIBABA_CLOUD_ACCESS_KEY_SECRET=<access_key_secret>

  • Windows系统配置方法

    新建环境变量文件，添加环境变量ALIBABA_CLOUD_ACCESS_KEY_ID和ALIBABA_CLOUD_ACCESS_KEY_SECRET，并写入已准备好的AccessKey ID和AccessKey Secret。然后重启Windows系统。本操作以Windows 10为例进行说明。

    1. 打开文件资源管理器，在此电脑上右键单击属性。

    2. 在右侧导航栏，单击高级系统配置。

    3. 在系统属性对话框的高级页签下，单击环境变量。

    4. 在环境变量对话框中，单击新建(W)。image.png

    5. 在弹出的新建系统变量对话框中，添加环境变量ALIBABA_CLOUD_ACCESS_KEY_ID和ALIBABA_CLOUD_ACCESS_KEY_SECRET，并写入已准备好的AccessKey ID和AccessKey Secret。

    6. 重启Windows系统，使配置生效。

常见的结果后处理

Mask视频融合

调用视频人像分割能够获取分割之后的Mask视频，该视频可以与另一张图片进行背景融合，实现人像的分割。

  1. 安装相关依赖，实现依赖OpenCV。更多信息，请参见OpenCV。

    pip install opencv-python

  2. 将分割后的视频下载到本地，与原视频和背景图一起放到data文件夹下。

    背景图：

    image

    相关代码如下： 

    import cv2
import numpy as np

#原视频路径
video_root = './data/video.mp4'
#调用视频人像分割返回的结果本地视频路径
mask_root = './data/mask.mp4'
video = cv2.VideoCapture(video_root)
mask = cv2.VideoCapture(mask_root)
rval, frame = video.read()
rval_mask, frame_mask = mask.read()
fps = video.get(cv2.CAP_PROP_FPS)
h, w = frame.shape[:2]
fourcc = cv2.VideoWriter_fourcc(*'mp4v')
video_writer = cv2.VideoWriter('com.mp4', fourcc, fps, (w, h))
num_frame = video.get(cv2.CAP_PROP_FRAME_COUNT)

#背景图路径
background_root = './data/img.jpg'
background = cv2.imread(background_root)
background = cv2.resize(background, (w, h))
for c in range(0,int(num_frame)):
        if (frame is None) or (frame_mask is None):
                continue
        fg_com = frame * (frame_mask/255) + background * (1-frame_mask/255)
        video_writer.write(fg_com.astype(np.uint8))
        rval, frame = video.read()
        rval_mask, frame_mask = mask.read()
video_writer.release()

    效果视频：

    视频人像分割后得到的视频人像和背景融合的相关代码，请参见com_back。

    说明

    代码解压后运行python com_back.py即可，目前示例代码中的背景图三通道的图都可以进行融合。
