Computer Vision Sandbox

All my personal, non-academic computer vision research lies here.

So far, all my projects are written in C++. This allows me to practice using standard, free tools to make fast, lightweight standalone applications that are relatively easy to integrate with hardware like GPUs and TPUs. Check out my setup at docs/setup.md

Libraries

Name	Installation instructions	License	Github Repository
OpenCV	official instructions as of 7/13/2020 (volatile)	3-clause BSD License	yes
GLAD	Included in project (Unofficial instructions) (path to KHR library modified)	Varies	Generator
GLFW	Included in project (Official instructions)	zlib license	yes
ImGui	Included in project (static library)	MIT License	yes

Note that, though my source code is released under the MIT license, cloning this repository may still bind you to the licenses of the libraries listed above.

Projects

Here are all my projects so far:

Name	Description
Hello World	A basic project that loads with OpenCV and displays it in a window
Hello GLFW	A basic project that creates a window and an OpenGL context with GLFW and GLAD
Hello ImGui	A basic project that uses the GLFW window created from project 02 to create a simple Gui with ImGui
GLFW and OpenCV	A combination of Projects 01 and 02, loading an image with OpenCV and displaying the generated OpenCV Mat with GLFW
GLFW and OpenCV and ImGui	A combination of Projects 03 and 04, loading an image with OpenCV and displaying the generated OpenCV Mat with GLFW on an ImGui window
Raytracing in One Weekend	My GUI setup, applied with the book Ray Tracing in One Weekend, in attempt to interactively render 3D images via ray tracing
Hello CUDA	A basic program written in CUDA C++
CUDA and OpenGL	A basic program written in CUDA to modify an OpenGL texture using a per-pixel function
OpenCV Video Template	A template program for video analysis with OpenCV
Convolution Benchmark	A whole suite of eight janky matrix convolution implementations in C. Plus benchmark software to assess my incompetence!
GL Game	Recreating a game to explore graphics programming with OpenGL

Make it Yours

This project can be a template for your projects too.

Each project is a folder under src/, which contains all source code for that project and a CMake script to build that code, as shown below and in the src folder:

src/
  01_Hello_World/   <----+
    CMakeLists.txt       |
    sources.cpp          |  The Hello World project
    headers.hpp          |__________________________
  02_Hello_GLFW/    --------------------------------
    CMakeLists.txt
    sources.cpp
    headers.hpp
  ...

The root-level build scripts search for subfolders of src with CMakeLists.txt and include them into the project, so no modifications to the other build scripts are necessary.

Notes:

• A template CMake file is available.
• I personally tend to copy one of the first few projects because they’re already minimal, buildable, runnable projects.
• Don’t set EXECUTABLE_NAME to be the same name in two different projects. CMake does not allow creating two executables with the same name.
• MEDIA_DIRECTORY can be used to get the full path of the asset folder in all files of all projects.
  • WARNING: this is a C macro and is only recalculated during builds
