Image Deduplicator 图像去重 Skill

功能概述

本skill使用图像哈希算法(phash/dhash/whash/ahash)进行图像级别的精确匹配去重。 通过计算每个图像的哈希值,识别并删除包含相同图像的重复文档样本。

触发条件

当用户请求以下任务时,应使用此skill:

  • 图像去重
  • 删除重复图片
  • 图片去重
  • 清理重复图像
  • 文档图像去重

核心参数说明

必需参数

参数说明
--input输入JSON文件路径
--output输出JSON文件路径

可选参数

参数说明默认值
--method图像哈希方法phash
--consider_text是否同时考虑文本哈希False
--image_key图像字段的键名images
--text_key文本字段的键名text

输入文件格式

[
  {
    "images": ["/path/to/image1.png", "/path/to/image2.jpg"]
  },
  {
    "images": ["/path/to/image3.jpg"]
  }
]

带文本的格式:

[
  {
    "images": ["/path/to/image1.png"],
    "text": "这是一段描述文字"
  },
  {
    "images": ["/path/to/image2.png"],
    "text": "另一段描述文字"
  }
]

哈希方法说明

方法说明
phash感知哈希,速度快,准确性高(默认)
dhash差值哈希
whash小波哈希
ahash平均哈希,最快但最粗糙

使用方法

基本用法

python scripts/run_image_deduplicator.py \
  --input ./input.json \
  --output ./output.json

使用指定哈希方法

python scripts/run_image_deduplicator.py \
  --input ./input.json \
  --output ./output.json \
  --method dhash

同时考虑文本去重

python scripts/run_image_deduplicator.py \
  --input ./input.json \
  --output ./output.json \
  --consider_text True

输出示例

命令行输出:

[OK] Image deduplication completed!
   Method: phash
   Consider text: False
   Original documents: 7
   Deduplicated documents: 3
   Removed duplicates: 4
   Input file: ./input.json
   Output file: ./output.json

输出JSON格式:

[
  {"images": ["/path/to/image1.png"]},
  {"images": ["/path/to/image2.jpg"]},
  {"images": ["/path/to/image3.jpg"]}
]

环境要求

安装依赖: 本SKILL使用依赖 data_juicer,请在调用前安装好python环境并安装data_juicer,可用以下指令进行安装:

pip install py-data-juicer

额外依赖:

pip install imagededup

注意事项

  1. 图像路径:输入JSON中的图像路径应为绝对路径或相对于工作目录的路径
  2. 哈希方法:默认使用 phash,适合大多数场景
  3. consider_text:设为 True 时,图像和文本都相同才算重复
  4. 图像格式:支持 PNG、JPG、JPEG 等常见图像格式
