Building a Media Detective for Contextual Image Discovery

说明与用途

Media Detective 自动从多个授权来源搜索上下文相关的图像和视频，去重、缓存查询并跟踪归属，简化内容创作者的媒体发现流程。

问题

Finding contextual, licensed images and videos for news or content creation is difficult because stock sites offer generic media and search engines return irrelevant results.

结果

The Media Detective delivers contextual, licensed media from multiple sources, eliminates duplicates, caches queries to respect rate limits, and tracks attribution, enabling creators to find relevant images and videos efficiently.

工作流

• Define the topic to search for
• Invoke Media Detective’s get_images_for_topic with desired count
• The detective queries Pexels, Pixabay, Wikimedia Commons, and Archive.org for images and videos
• Results are deduplicated using perceptual hashing
• Cached queries reduce API calls
• Attribution information is stored for each media item
• Return the curated list of media to the user

证据

The detective searches all sources for contextual images

来源

To avoid using the same image twice, the detective uses perceptual hashing (pHash 8x8 - 16 hex chars).

来源

The detective caches recent queries (2 hours) to avoid API rate limits.
