Overview

An AI-powered image captioning system that combines Computer Vision and Natural Language Processing to automatically generate human-like descriptions of images. The project demonstrates deep learning expertise and the practical application of neural networks for real-world problems.

Key Features

  • CNN + LSTM Architecture — Utilizes Convolutional Neural Networks (CNN) for extracting visual features from images and Long Short-Term Memory (LSTM) networks for generating sequential text descriptions.
  • Large-Scale Training — Model trained on extensive image-caption datasets to learn diverse vocabulary and contextual understanding for accurate caption generation.
  • Interactive Application — User-friendly app that allows real-time image upload and instant caption generation, demonstrating the model's practical applicability.
  • Transfer Learning — Leverages pre-trained CNN models (like VGG16 or ResNet) for robust feature extraction, improving accuracy and reducing training time.
  • Beam Search Decoding — Implements advanced decoding strategies to generate more accurate and natural-sounding captions.
