Set up your working directory in Google Drive for the image enhancement project, download the image enhancement folder, and include training set, validation set, evaluation set folders with the code.ipynb.
Explore the load data set of 500 image pairs for low-light photography enhancement, with training, evaluation, and validation subsets containing high and low subfolders, all sized 400 by 600.
Import essential libraries for image processing and deep learning, including os, glob, PIL, OpenCV, NumPy, Matplotlib, TensorFlow, Keras, and the layers module.
Define file paths for training, validation, and test data using the globe function, creating sorted lists of train lowlight images and train enhanced images.
Compile a deep learning image enhancement model in TensorFlow or Keras, using Adam optimizer with a learning rate of 1e-4, Charbonier loss, and PSNR as the monitoring metric during training.
Train a deep learning model with TensorFlow or Keras on train and validation datasets for 50 epochs, using a callback that reduces learning rate when val PSNR stops improving.
Plot the training and validation psnr over epochs with matplotlib to compare how psnr evolves across approaches, using a legend to distinguish curves and assess reconstructed image quality.
Apply a pre-trained model to enhance images, preprocess inputs to numpy, normalize to 0-1, add a batch dimension, run the model, and convert results back to a PIL image.
