Building a Media Detective for Contextual Image Discovery

Описание и применение

Система Media Detective автоматически ищет контекстные изображения и видео из нескольких лицензированных источников, устраняет дубликаты, кэширует запросы и отслеживает атрибуцию, облегчая поиск подходящего медиа.

Задача

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.

Результат

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.

Рабочий процесс

• 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
