AI Photo Album Web Application

This application is an intelligent photo album that allows users to search for images using natural language through both text and voice. Users can upload images and search for images by people, objects, actions, landmarks, and much more.

Features:

• Natural Language Search through Text & Voice
• Powered by AWS Lex, OpenSearch, Rekognition, Lambda, and S3
• Auto-indexing of images when uploaded
• Ability to attach custom labels to photos
• Voice accessibility in frontend

Implementation Outline:

1. OpenSearch Setup: Deployed an OpenSearch instance inside a VPC for secure and scalable searching.
2. Image Upload & Indexing: Upload images to an S3 bucket and trigger Lambda functions for indexing in OpenSearch.
3. Natural Language Search: Utilized Amazon Lex for search queries and fetch results from OpenSearch.
4. API Layer: Implement API Gateway for two main functionalities - uploading photos and searching.
5. Frontend: A user-friendly frontend for search and upload. Can also specify custom labels during upload.
6. Voice Accessibility: Frontend implementation to allow voice-based searches using Amazon Transcribe.
7. Continuous Deployment: Used AWS CodePipeline for seamless CI/CD of the application.
8. Infrastructure as Code: Used AWS CloudFormation for replicable and managed infrastructure deployment.
