Borde - GPU-accelerated edge detection using CUDA

Borde is a GPU-accelerated edge detection app written in C++ and CUDA. It is designed to be fast, easy to use, and easy to integrate into existing projects. Borde is licensed under the MIT license.

Features and Limitations 🎭

Features:

• Well-Documented: Borde is well-documented.
• Easy to Use: Borde is easy to use.
• Configurable: Borde is configurable and allows you to change the parameters of the edge detection algorithm.

Limitations:

• Only PNG: Borde only supports PNG images for now.
• Only Sobel: Borde only supports the Sobel operator for now.

Requirements 📋

CPU:

• CMake 3.10 or higher
• GCC 7.5.0 or higher

GPU:

• CUDA 10.1 or higher

Compiling 🔨

To compile Borde, Go to ./runners and run the following commands:

For CPU version:

$ make cpu

For GPU version:

$ make gpu

after compiling, you can see the 3 executables in ./runners directory.

1. brightness_filter_runner_cpu/gpu : for brightness filter
2. grayscale_filter_runner_cpu/gpu : for grayscale filter
3. sobel_filter_runner_cpu/gpu : for sobel filter

Running 🏃

After compiling, you can run the executables in ./runners directory.

Grayscale Filter

Run the Grayscale Filter with no arguments to see the usage and default values:

$ ./grayscale_filter_runner_cpu/gpu.out

Available arguments:

Usage: ./grayscale_filter_runner_cpu/gpu.out <input_path> <input_filename> <result_path>

Brightness Filter

Run the Brightness Filter with no arguments to see the usage and default values:

$ ./brightness_filter_runner_cpu/gpu.out

Available arguments:

Usage: ./brightness_filter_runner_cpu/gpu.out <input_path> <input_filename> <result_path> <brightness_change>

Sobel Filter

Run the Sobel Filter with no arguments to see the usage and default values:

$ ./sobel_filter_runner_cpu/gpu.out

Available arguments:

Usage: ./sobel_filter_runner_cpu/gpu.out <input_path> <input_filename> <result_path> <threshold> <scale>

Default Values 📄

You can check and set the default values in ./config.h file.
