Visual Search Technology Revolutionizes Ecommerce
In ecommerce, visual search technology has revolutionized the way customers find products by enabling them to search for products using images instead of text. Shoppers often have a clear visual idea of what they want but struggle to describe it in words, leading to inefficient and broad text-based search results.
Reverse Image Search Engine
A reverse image search engine enables users to upload an image to find related information instead of using text-based queries. It works by analyzing the visual content to find similar images in its database. Companies such as Amazon use this technology to allow users to use a photo or other image to search for similar products on their ecommerce websites.
Solution Overview
The solution outlines how to build a reverse image search engine to retrieve similar images based on input image queries. This post demonstrates a guide for using Amazon Titan Multimodal Embeddings to embed images, store these embeddings in an OpenSearch Serverless vector index, and use Amazon Rekognition to extract key objects from images for querying the index.
Prerequisites
To implement the proposed solution, make sure that you have the following:
- An AWS account and a working knowledge of FMs, Amazon Bedrock, Amazon SageMaker, Amazon OpenSearch Service, Amazon S3, and AWS Identity and Access Management (IAM).
- The AWS Command Line Interface (AWS CLI) installed on your machine to upload the dataset to Amazon S3.
- Amazon Titan Multimodal Embeddings model access in Amazon Bedrock.
- An Amazon SageMaker Studio domain.
- An Amazon OpenSearch Serverless collection.
- The GitHub repo cloned to the Amazon SageMaker Studio instance.
Generate Embeddings
Use Amazon Titan Multimodal Embeddings to generate embeddings for the stored images.
Store Embeddings
Ingest the generated embeddings into an OpenSearch Serverless vector index, which serves as the vector database for the solution.
Image Analysis
Use Amazon Rekognition to analyze the product images and extract labels and bounding boxes for these images. These extracted objects will then be saved as separate images, which can be used for the query.
Convert Search Query to an Embedding
Convert the user’s image search query into an embedding using Amazon Titan Multimodal Embeddings.
Run Similarity Search
Perform a similarity search on the vector database to find product images that closely match the search query embedding.
Display Results
Display the top K similar results to the user.
Conclusion
By combining the power of Amazon Rekognition for object detection and extraction, Amazon Titan Multimodal Embeddings for generating vector representations, and Amazon OpenSearch Serverless for efficient vector indexing and search capabilities, you successfully created a robust reverse image search engine. This solution enhances product recommendations by providing precise and relevant results based on visual queries, thereby significantly improving the user experience for ecommerce solutions.
