Image processor

Program written on C++ with OpenGL's GLSL shaders to transform images by applying kernel convolutions.

What is this?

Application created to process texture with various kernels:

• Edge detecting kernels (Prewitt, Sobel, Scharr)
• Smoothing kernels (Average)
• Denoising kernels (Median)

Created with:

• SDL2 and SDL2_image
• ImGui
• OpenGL

How to build

Requirements:

• OpenGL >= 4.2, or otherwise:
  • change kOpenGlVersion and kGlslVersion in application_config.h)
  • change API version in glad2_loader/CMakeLists.txt
  • fix .frag shaders in shaders/
• C++ compiler supporting C++20 standard
• CMake >= 3.15
  • otherwise, try change VERSION in CMakeLists.txt
• Installed SDL2 & SDL2_image libraries

Clone project with submodules (choose one of the repositories):

git clone https://github.com/ValeryKameko/image-processor --recurse-submodules
git clone https://gitlab.com/ValeryKameko/image-processor --recurse-submodules

Build CMake project:

cd    ./image-processor
mkdir ./cmake-build-release
cd    ./cmake-build-release
cmake .. -DCMAKE_BUILD_TYPE=Release

To run application:

cd ./bin

# for WINDOWS
./image-processor.exe

# for Linux
./image-processor

Tested on:

• Windows (GNU GCC 9.0 MinGW, CMake 3.15, OpenGL 4.6)
