Live CV is a computer vision coding environment that displays results while you code. It can be used to interact, link and adjust algorithms in order to create quick solutions within it's domain.

The application is built using QtQuick, and uses Open CV library in the back to do the actual processing, kind of like a QML wrapper for the Open CV library.

An API is also available to link already built algorithms to Live CV's interface by simply exposing configurable variables to Qt's meta object system.

Installation and getting started

To get started, simply download the application from Live CV's website, extract the archive, and you're ready to go. Step by step instructions are also found in the download section.

Compiling

Live CV requires qt and open cv libraries to compile. You can use qmake to generate the makefile, then run make or nmake to build:

cd build
qmake -r
make (or nmake)

The executable and plugins will be found in the application directory.

Contributing

There's an organization on github created for Live CV plugins and projects, so anyone looking to contribute is always welcome. This section offers a quick overview on contributing, and there are simple quickstart issues available for anyone looking to start. Most of them deal with wrapping an Open CV functions and adding a sample. There are issues marked with easy which are similar, but may have a few more displayable parameters or require a bit more processing.

There's a forum available for discussions on live cv's website.
