📸 PicMatch: Your Visual Search Companion 🔍

PicMatch lets you effortlessly search through your image archive using either a text description or another image as your query. Find those needle-in-a-haystack photos in a flash! ✨

Try PicMatch image search with 25,000 Unsplash images on this 🤗 Space

🚀 Getting Started:

1. Prerequisites: Ensure you have Python 3.9 or higher installed on your system. 🐍

2. Create a Virtual Environment:

   python -m venv env

3. Activate the Environment:

   source ./venv/bin/activate 

4. Install Dependencies:

   python -m pip install -r requirements.txt

5. Start the App (with Sample Data):

   python app.py

6. Open Your Browser: Head to localhost:7860 to access the PicMatch interface. 🌐

📂 Data: Organize Your Visual Treasures

Make sure you have the following folders in your project's root directory:

data
├── images   
└── features

🛠️ Image Pipeline: Download & Process with Speed ⚡

The engine/download_data.py Python script streamlines downloading and processing images from a list of URLs. It's designed for performance and reliability:

• Async Operations: Uses asyncio for concurrent image downloading and processing. ⏩
• Rate Limiting: Follows API usage rules to prevent blocks with a RateLimiter. 🚦
• Parallel Resizing: Employs a ProcessPoolExecutor for fast image resizing. ⚙️
• State Management: Saves progress in a JSON file so you can resume later. 💾

🗝️ Key Components:

• ImagePipeline Class: Manages the entire pipeline, its state, and rate limiting. 🎛️
• Functions: Handle URL feeding (url_feeder), downloading (image_downloader), and processing (image_processor). 📥
• ImageSaver Class: Defines how images are processed and saved. 🖼️
• resize_image Function: Ensures image resizing maintains the correct aspect ratio. 📏

🏃 How it Works:

1. Start: Configure the pipeline with your URL list, download limits, and rate settings.
2. Feed URLs: Asynchronously read URLs from your file.
3. Download: Download images concurrently while respecting rate limits.
4. Process: Save the original images and resize them in parallel.
5. Save State: Regularly save progress to avoid starting over if interrupted.

To get the sample data run the command

cd engine && python download_data.py

✨ Feature Creation: Making Your Images Searchable ✨

This step prepares your images for searching. We generate two types of embeddings:

• Visual Embeddings (CLIP): Capture the visual content of your images. 👁️‍🗨️
• Textual Embeddings: Create embeddings from image captions for text-based search. 💬

To generate these features run the command

cd engine && python generate_features.py

This process uses these awesome models from Hugging Face:

• TinyCLIP: wkcn/TinyCLIP-ViT-8M-16-Text-3M-YFCC15M
• BLIP Image Captioning: Salesforce/blip-image-captioning-base
• SentenceTransformer: all-MiniLM-L6-v2

⚡ Asynchronous Feature Extraction: Supercharge Your Process ⚡

This script extracts image features (both visual and textual) efficiently:

• Asynchronous: Loads images, extracts features, and saves them concurrently. ⚡
• Dual Embeddings: Creates both CLIP (visual) and caption (textual) embeddings. 🖼️📝
• Checkpoints: Keeps track of progress and allows resuming from interruptions. 🔄
• Parallel: Uses multiple CPU cores for feature extraction. ⚙️

📊 Vector Database Module: Milvus for Fast Search 🚤

This module connects to the Milvus vector database to store and search your image embeddings:

• Milvus: A high-performance database built for handling vector data. 📊
• Easy Interface: Provides a simple way to manage embeddings and perform searches. 🔍
• Single Server: Ensures only one Milvus server is running for efficiency.
• Indexing: Automatically creates an index to speed up your searches. 🚀
• Similarity Search: Find the most similar images using cosine similarity. 💯
