Image Captioning

Implementation of a Image Captioning Model using Transfer Learning and Recurrent Neural Networks

Open In Colab

Requirements

The following libraries are required to run the code :

  1. Tensorflow
  2. Keras
  3. Numpy
  4. Pandas
  5. OpenCV
  6. Matplotlib
  7. Tqdm

The above mentioned packages can be installed by executing pip install -r requirements.txt

Dataset

The neural network has been trained on Flicker8K Dataset. This dataset has been obtained from Kaggle. The link to this dataset is given below. Please download the dataset from the given link and place them in your project directory.

Link : https://www.kaggle.com/ming666/flicker8k-dataset

Training

Training the neural network takes a really long time. Training depends on your system's capability. The neural network has been trained on Nvidia Tesla K80 GPUs for about 3 days. This could vary from system to system. It is recommended to use a GPU of some sort to train this model.

I would like to thank Kaggle for letting me use their GPUs for training my neural network.

Contribution

Contributers are free to make changes in the code either to imporve it or correct some of the bugs that may be present in the code. Please make a pull request before you edit the code. Avoid making changes in the master branch.
