This project aims to develop a deep learning model to dehaze images. Image dehazing is pivotal for enhancing visual clarity in various applications in computer vision tasks. The model is constructed using an encoder-decoder architecture in PyTorch.
We are utilizing the Dense-Haze dataset available on Kaggle. This dataset contains 55 pairs of hazy and non-hazy images, making it a suitable benchmark for image dehazing tasks.
-
Data Preprocessing:
- Resize images and normalize pixel values.
-
Model Development:

Results Visualization:
- Showcase original, hazy, and dehazed images side by side.
- Plot training loss and validation loss across epochs.
-
Optimization (if necessary):
- Tune hyperparameters, such as learning rate, batch size, and number of epochs.
- Modify the model architecture by adding more layers or changing layer configurations.
- Implement data augmentation to artificially increase the training dataset size and robustness.
