How Image Search Works (Metadata vs CLIP Approach Explained)
Have you ever wondered how Google Images or Pinterest can instantly find visually similar images among millions of photos? In this video, I explain the core concepts of an Image Search System (ISS) — what it is, how it works, and two key approaches:
1. Metadata-based image search (traditional approach)
2. CLIP-based image search (modern AI approach)
There’s no coding demo — just a clear, theory-based explanation of the ideas behind image search technology.
Topics covered:
What is an Image Search System?
How metadata tagging works for image search.
Limitations of metadata-based search.
How CLIP (Contrastive Language–Image Pretraining) revolutionizes image search.
Why modern platforms like Pinterest and Google Images rely on AI-based approaches.
