Abstract

This project makes use of Google Generative AI, FAISS, and LangChain to facilitate the effective extraction, retrieval, and analysis of text from documents and pictures. The system uses optical character recognition (OCR) technology to extract text from photos and analyze it for context-aware answer creation and intelligent search. Fast and scalable semantic search across big datasets is made possible by FAISS, which guarantees efficient vector-based retrieval. Furthermore, Google Generative AI improves natural language comprehension, enabling perceptive analysis of retrieved material. Information access will be smooth, intelligent, and effective with this project's AI-powered document search, image-based text extraction, chatbot interactions, automated data indexing, real-time information retrieval, and knowledge management features.
Key Features
Text Extraction: Extract text from images using OCR or pre-loaded text files.

Keyword Search: Perform case-insensitive keyword searches within extracted text.

Image Analysis: Analyze images using Google Generative AI (Gemini Pro Vision) to extract relevant information.

Interactive UI: Use Gradio to create a user-friendly interface for uploading images, entering keywords, and viewing results.

Deployment: Deploy the application on platforms like Hugging Face Spaces or Google Colab.

Technologies Used
LangChain: For building the text processing and retrieval pipeline.

Google Generative AI: For text and image analysis (Gemini Pro and Gemini Pro Vision).

Gradio: For creating an interactive web interface.

FAISS: For efficient vector storage and retrieval of text embeddings.

Python: The primary programming language for implementation.

Methodology

A methodical pipeline for text extraction and analysis from photographs is part of the project's approach. First, textual material from photographs is recognized and transformed into machine-readable text using optical character recognition, or OCR. LangChain is then used to handle this extracted text, structuring and organizing the data for easier understanding. Google Generative AI is then used to create embeddings, which convert textual data into vector representations. FAISS effectively stores and indexes these embeddings, allowing for quick and precise similarity searches. Lastly, by matching user queries with pertinent extracted material, the system enables intelligent retrieval, guaranteeing a search experience that is optimized and contextually aware. High accuracy, scalability, and efficiency are guaranteed when managing substantial amounts of textual data based on images using this method.

Results

The project's outcomes show that text may be accurately and efficiently extracted from photos, followed by insightful analysis and retrieval. High text recognition precision is ensured by the OCR's effective identification and conversion of textual material. Structured processing is made possible by the inclusion of LangChain, which enhances the collected data's organization and usefulness.
Better contextual matching is made possible by the use of Google Generative AI for embeddings, which improves semantic comprehension. Fast and pertinent search results are made possible by FAISS indexing, which dramatically increases retrieval speed. The system is appropriate for applications in document processing, information retrieval, and knowledge management as it efficiently handles image-based textual data and offers users an intuitive and optimal search experience.
