本文檔為您介紹視頻人像分割能力常用語言和常見情況的示例代碼。

說明

  • 您可以進(jìn)入在線咨詢獲取在線人工幫助。

  • 阿里云視覺智能開放平臺(tái)視覺AI能力API接入、接口使用或問題咨詢等，請(qǐng)通過釘釘群（23109592）加入阿里云視覺智能開放平臺(tái)咨詢?nèi)郝?lián)系我們。

能力介紹

關(guān)于視頻人像分割能力的功能介紹以及具體調(diào)用參數(shù)說明，請(qǐng)參見視頻人像分割。

SDK包安裝

常見語言的SDK依賴包信息，請(qǐng)參見SDK總覽。

配置環(huán)境變量

配置環(huán)境變量ALIBABA_CLOUD_ACCESS_KEY_ID和ALIBABA_CLOUD_ACCESS_KEY_SECRET。

重要

  • 阿里云賬號(hào)AccessKey擁有所有API的訪問權(quán)限，建議您使用RAM用戶進(jìn)行API訪問或日常運(yùn)維，具體操作，請(qǐng)參見創(chuàng)建RAM用戶。

  • 請(qǐng)不要將AccessKey ID和AccessKey Secret保存到工程代碼里，否則可能導(dǎo)致AccessKey泄露，威脅您賬號(hào)下所有資源的安全。

  • Linux和macOS系統(tǒng)配置方法

    1. 在IntelliJ IDEA中打開終端Terminal。

    2. 執(zhí)行以下命令，配置環(huán)境變量。

      <access_key_id>需替換為您RAM用戶的AccessKey ID，<access_key_secret>替換為您RAM用戶的AccessKey Secret。如果后續(xù)需要進(jìn)行更多權(quán)限相關(guān)的配置，具體操作請(qǐng)參見使用RAM Policy控制訪問權(quán)限。

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

  • Windows系統(tǒng)配置方法

    新建環(huán)境變量文件，添加環(huán)境變量ALIBABA_CLOUD_ACCESS_KEY_ID和ALIBABA_CLOUD_ACCESS_KEY_SECRET，并寫入已準(zhǔn)備好的AccessKey ID和AccessKey Secret。然后重啟Windows系統(tǒng)。本操作以Windows 10為例進(jìn)行說明。

    1. 打開文件資源管理器，在此電腦上右鍵單擊屬性。

    2. 在右側(cè)導(dǎo)航欄，單擊高級(jí)系統(tǒng)配置。

    3. 在系統(tǒng)屬性對(duì)話框的高級(jí)頁簽下，單擊環(huán)境變量。

    4. 在環(huán)境變量對(duì)話框中，單擊新建(W)。image.png

    5. 在彈出的新建系統(tǒng)變量對(duì)話框中，添加環(huán)境變量ALIBABA_CLOUD_ACCESS_KEY_ID和ALIBABA_CLOUD_ACCESS_KEY_SECRET，并寫入已準(zhǔn)備好的AccessKey ID和AccessKey Secret。

    6. 重啟Windows系統(tǒng)，使配置生效。

常見的結(jié)果后處理

Mask視頻融合

調(diào)用視頻人像分割能夠獲取分割之后的Mask視頻，該視頻可以與另一張圖片進(jìn)行背景融合，實(shí)現(xiàn)人像的分割。

  1. 安裝相關(guān)依賴，實(shí)現(xiàn)依賴OpenCV。更多信息，請(qǐng)參見OpenCV。

    pip install opencv-python

  2. 將分割后的視頻下載到本地，與原視頻和背景圖一起放到data文件夾下。

    背景圖：

    image

    相關(guān)代碼如下： 

    import cv2
import numpy as np

#原視頻路徑
video_root = './data/video.mp4'
#調(diào)用視頻人像分割返回的結(jié)果本地視頻路徑
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)

#背景圖路徑
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()

    效果視頻：

    視頻人像分割后得到的視頻人像和背景融合的相關(guān)代碼，請(qǐng)參見com_back。

    說明

    代碼解壓后運(yùn)行python com_back.py即可，目前示例代碼中的背景圖三通道的圖都可以進(jìn)行融合。
