A Practical True Shot Noise Generator

This repository generates true shot noise while taking into consideration image sensor Full-well and resolution. It is described in Medium article https://medium.com/@erezposner/how-to-create-awesome-noise-that-is-actually-real-cf178c9f0ae0?sk=8d74c4bce579b06b498a655a528d4dfd

Getting Started

These instructions will explain how to use the Practical True Shot Noise Generator project.

Prerequisites

• MATLAB >=2015a

Project Structure

• photoelectrons2graylevel.m - function to convert number of photoelectrons into pixel gray level value
• graylevel2photoelectrons.m - function to convert pixel gray level value into number of photoelectrons
• custome_poissrnd.m - a Possion process random number generator based on Donald Knuth - https://en.wikipedia.org/wiki/Poisson_distribution#Generating_Poisson-distributed_random_variables

Running the sample code

Now you should main.m to make sure that the project works correctly.

The test takes a clean image as input and produce half clean half noisy image.
