blurrifier

Educational-purpose multi-threaded image blurrifier.

Currently, only jpeg images are supported using libjpeg.

Usage

1. Configure

   You can configure

   • input image name (INPUT_IMAGE_FILENAME)
   • output images name (OUTPUT_IMAGE_FILENAME)
   • number of worker threads (NUM_THREADS)
   • convolution kernel window radius (KERNEL_RADIUS)

   configuration variables in config.h file.

2. Build

   cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
   cmake --build build

   Change Release to Debug in order to include debugg symbol files with output executable.

3. Run

   ./build/blurrifier

Development

You'll need CMake and a C compiler. I used CMake version 3.20.1 and clang version 11.1.0. If you want to use another compiler, set its path in CMakeLists.txt file (CMAKE_C_COMPILER configuration variable).
