Demos related to OpenGL, Qt, OpenCV and other X technologies.

A C++/Eigen implementation of Linear Regression based on Daniel Shiffman's tutorials. Data is plotted with Madplotlib.

This is a OpenGL/Qt demo that renders the Ingress logo on a texture and performs a blur to add a cool effect to the logo.

An application that shows how to create a Qt window to display videos loaded with OpenCV.

A simple Qt/OpenCV example that displays an image and the RGB values of a pixel based on the mouse coordinates.

This application uses OpenCV to retrieve frames from the camera and display them on a QGLWidget.

A Qt application that uses UtilPipeline (Intel® Perceptual Computing SDK 2013) for gesture recognition. This one is Windows only!

An app that implements the Displacement Map Filter to distort a movie clip.

A simple watershed segmentation example using distance transform to segment beans.

A C++/OpenCV port of a cool Python application that performs Oranges vs Apples classification using LDA.

An application that prints data from a serial (COM) port connected to an Arduino.

An application based on "Color Basics" from Kinect for Windows SDK 1.8. This demo shows how to display the Color Stream on your Qt application.

A Qt implementation of FPS-based and Time-based animation techniques, as explained by Steven Lambert: http://blog.sklambert.com/using-time-based-animation-implement/

A demo that takes a grayscale image as input and performs a smooth color transition from a color palette using linear interpolation.
