# Nighttime image enhancement using a new illumination boost algorithm Repository which replicates the results obtained by Al-Ameen, Zohair in his paper entitled _[Nighttime image enhancement using a new illumination boost algorithm](https://ieeexplore.ieee.org/document/8741330)_, published at [IET Image Processing Journal](https://digital-library.theiet.org/content/journals/iet-ipr). The code was implemented using MATLAB, following the steps presented in the paper. ## Usage The [`illumination_boost.m`](./illumination_boost.m) file contains the main (and only) function for the algorithm. It accepts an RGB image, and a Lambda parameter used in equations `4` and `6` in the paper, which, according to the paper, acquire best results with values between 2 and 7. It returns an RGB image with `double` type. A test file named [`test_illumination_boost.m`](./test_illumination_boost.m) is made available, to test the function with the images available in the [`input_images`](./input_images/) folder, varying the lambda parameter from 2 to 6. There is also the file [`plot_with_histogram.m`](./plot_with_histogram.m) which generates histograms for the base image and the enhanced one, given an image and a lambda parameter. ## Results Several results are available in the [`output_images`](./output_images/) folder, and some of them are displayed below:       ## Disclaimer This repository is not endorssed and/or affiliated in any way to Al-Ameen, Zohair. The paper was replicated for purely didactic purposes.
