图片模糊处理

更新时间:

图片模糊处理可以对一张图片的特定区域进行马赛克、高斯模糊或纯色块填充操作,用于隐私保护。本文介绍如何使用图片模糊处理功能。

前提条件

使用方法

调用AddImageMosaic - 添加图片马赛克接口对图片进行模糊处理。

图片处理信息

  • IMM项目名称:test-project

  • 待处理图片的存储地址:oss://test-bucket/test-object.jpg

  • 处理框信息:使用宽度和高度为100 px的方形马赛克小块处理图片

  • 输出图片的格式:jpg

  • 处理后图片的存储地址:oss://test-bucket/test-target-object.jpg

  • 图片示例:

    test-object

请求示例

{
    "ProjectName": "test-project",
    "SourceURI": "oss://test-bucket/test-object.jpg",
    "TargetURI": "oss://test-bucket/test-target-object.jpg",
    "ImageFormat": "jpg",
    "Quality": "81",
    "Targets": "[{\"Type\": \"square\", \"Boundary\": {\"ReferPos\": \"topleft\", \"X\": 20, \"Y\": 20, \"Height\": 100, \"Width\": 100}, \"MosaicRadius\": 10, \"BlurRadius\": 5, \"Sigma\": 1, \"Color\": \"black\"}]"
}

返回示例

{
  "RequestId" : "5F2389FE-A5E3-076F-B071-43A33*****",
}

处理后图片test-object
