Image Search:What is Image Search

Last Updated:Apr 01, 2026

Image Search lets you build a visual search engine powered by deep learning and computer vision. Submit a query image via the API, and Image Search returns visually similar images from your gallery — no keywords required.

Typical applications include snap shopping (let users photograph a product to find it in your catalog), product recommendations, similar-image recommendations, and copyright protection.

How it works

  1. Add reference images to an image gallery managed by Image Search.

  2. Submit a query image via the API.

  3. Image Search extracts image features, compares them against the gallery, and returns a list of similar images.

Service types

Image Search offers two service types. Select one when you create an instance — you cannot change the service type afterward.

Service typeWhat it searchesBest for
Product image searchA product image galleryFinding identical or similar products; returning associated product information
Generic image searchA large general-purpose image galleryMatching images by subjects or visual elements across any domain
