Kernel convolution Image processing application with GLSL shaders written on C++

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
