V4D
V4D is a high performance visualization module for OpenCV. It features vector graphics using NanoVG a GUI based on NanoGUI and (on supported systems) OpenCL/OpenGL and OpenCL/VAAPI interoperability. It should be included in OpenCV-contrib once it is ready.
What is V4D?
V4D is a way of writing graphical (on- and offscreen) high performance applications with OpenCV. It is light-weight and unencumbered by QT or GTK licenses.
Why V4D?
Please refer to the online demos to see at a glance what it can do for you.
- OpenGL: Easy access to OpenGL.
- GUI: Simple yet powerful user interfaces through NanoGUI.
- Vector graphics: Elegant and fast vector graphics through NanoVG.
- Font rendering: Loading of TTF-fonts and sophisticated rendering options.
- Video pipeline: Through a simple Source/Sink system videos can be displayed, edited and saved.
- Hardware acceleration: Automatic hardware acceleration usage where possible. (e.g. cl-gl sharing and VAAPI). Actually it is possible to write programs that run almost entirely on the GPU, given driver-features are available.
- No more highgui with it's heavy dependencies, licenses and limitations.
- WebAssembly
Online Demos
Please note that the following online demos are slower and/or have less features than the native versions.
