Content-Based Image Retrieval (CBIR) Framework

Overview

This project presents a Hybrid Deep Hashing and Metric Space Partitioning Framework for scalable Content-Based Image Retrieval (CBIR). It integrates unsupervised representation learning with VP-Tree optimization to enhance retrieval accuracy and efficiency.

Features

• Autoencoder-Based Feature Extraction: Generates compact and semantically meaningful image representations.
• Hybrid Search Mechanism: Uses Euclidean-based nearest neighbor search (O(N log N)) for moderate-scale datasets and VP-Tree-based indexing (O(log N)) for large-scale retrieval.
• Deep Hashing Techniques: Enhances retrieval precision while maintaining computational efficiency.
• Scalability and Speed Optimization: Reduces search complexity without compromising retrieval accuracy.

Installation

Prerequisites

Ensure you have the following installed:

• Python 3.8+
• PyTorch
• NumPy
• OpenCV
• Matplotlib
• scikit-learn

Setup

Results

The proposed model achieves higher mean average precision (mAP), reduced search latency, and improved storage efficiency compared to traditional CBIR techniques. Benchmark results on CIFAR-10 and ImageNet datasets demonstrate its superior performance.The experimental results validate the superiority of the proposed method, outperforming traditional CBIR techniques in terms of retrieval speed, accuracy, and computational efficiency. The proposed model achieves:

• 96.1% mAP
• 94.8% F1-Score
