UnSee : Blur any Image you like!!

This repository has source files for UnSee which was just a C++ Project (Nothing Fancy). It uses OpenCV to read images and a custom implementation of Gaussian Blur inspired from this article I found while looking for fast blurring methods because the default one provided by OpenCV was not fast enough..

---

1. Building....

  1. Pre-requisites :

You need to have Linux(preferably Ubuntu 22.04) because I used WSL2, then install cmake, OpenCV, and build-essentials etc.

Some resilience because OpenCV generally has linking problems :D

  2. Actual Building and Running:

Use the following commands :

git clone https://github.com/DarshPareek/UnSee
cd UnSee
cmake --build .

This Should generate a file(executable) named UnSee
To run it :

./UnSee

Then just follow the prompts :D.

2. Release....

You can directly download program.o from the releases and run it using the following commands :

chmod +x program.o
./program.o

3. About Source Files

main.cpp : contains the basic loop to spare you from re-running the executable again and again for different images and blur strengths also makes calls to fastGauss.cpp.

fastGauss.cpp : accepts the image path and blur strength from main.cpp and does all the crazy math that is required to do a Gaussian Blur. I implemented this js-version into C++. Call me crazy but this is way faster from what OpenCV provides and there is still scope for heavy optimization in my code.

CMakeList.txt : contains the bare-minimum stuff to build this project. It links OpenCV libraries and does a whole lot of other stuff.

4. Future....

1. I might build a windows version. (windows is a niche operating system used by gamers)

2. I might build a backend server (in C++ or Python) and a frontend GUI in HTML, CSS and JS to allow users to upload images on the localhost and choose blur strength using a slider while the image updates in real-time.
