本文档为您介绍通用图像分割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

关于通用图像分割的功能介绍以及具体调用参数说明，请参见通用分割。

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。

常见的处理后结果

背景融合

调用通用分割后，可以获取主体与背景分割后的前景物体图（4通道），可以与另一张图片进行背景融合。

以python语言为例进行代码演示。

  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. 将分割后的图片下载到本地，与原图和背景图一起放到data文件夹下。

    背景图：image

    相关代码如下：

    import argparse
import math
import cv2
from typing import List
import numpy as np
import urllib.request
#背景变换
def change_background_demo(
        args: List[str],
) -> None:
    assert (args.param is not None and len(args.param) > 3), "parameters wrong, use -h for details!"
    of_file = args.param[3]
    [sc_image, seg_img, bg_image] = [cv2.imread(img_file, cv2.IMREAD_UNCHANGED)
                            for img_file in args.param[0:3]]
    # 将分割结果进行新背景融合
    rst_image = image_merge_background(sc_image, seg_img, bg_image)
    # 保存结果到本地
    cv2.imwrite(of_file, rst_image)
#分割后的图合并到背景图中
def image_merge_background(sc_image, png_image, bg_image):
    assert (sc_image is not None and png_image is not None and bg_image is not None), "read image input error!"
    h, w, c = sc_image.shape
    # keep sc_image, png_image and bg_image same size
    viapi_image = cv2.resize(png_image, (w, h))
    bg_image = cv2.resize(bg_image, (w, h))
    if len(viapi_image.shape) == 2:
        mask = viapi_image[:, :, np.newaxis]
    elif viapi_image.shape[2] == 4:
        mask = viapi_image[:, :, 3:4]
    elif viapi_image.shape[2] == 3:
        mask = viapi_image[:, :, 0:1]
    else:
        raise Exception("invalid image mask!")
    mask = mask / 255.0
    # merge background（合并背景）
    sc_image = sc_image.astype(float)
    bg_image = bg_image.astype(float)
    rst_image = (sc_image - bg_image) * mask + bg_image
    rst_image = np.clip(rst_image, 0, 255)
    return rst_image
def define_options():
    parser = argparse.ArgumentParser(description='Human segmentation examples.')
    parser.add_argument('-p', '--param', nargs=4
                            , default=['./data/source.jpg', './data/output.png', './data/background.jpg', 'result.jpg']
                            , type=str
                            , help=('source_image_path output_image_path background_path result_path'))
    args = parser.parse_args()
    return args
if __name__ == '__main__':
    args = define_options()
    change_background_demo(args)

    效果图如下：

    image

    背景融合的相关代码，请参见merge_background。

    说明

    代码解压后运行python merge_background.py即可，目前示例代码中的背景图需要使用JPG格式图片。
