3 | | -Qt3D/QML implementation of water reflection/refraction using clipping planes. |
| 5 | +Demos related to **OpenGL**, **Qt/QML**, **OpenCV** and other X technologies. |

|
5 | | -The water is just a simple a `PlaneMesh` entity and most of the work is done by `water.frag`: |
6 | | - |
7 | | -- DuDv map is used to create distortions on the water surface; |
8 | | -- The Fresnel effect allows the water to be more transparent when looking from above; |
9 | | -- Specular highlights are based on a Normal map; |
10 | | -- The mesh of the water is not changed at all by the vertex shader; |

| 10 | +**cvFruitClassification** | C++/OpenCV port of [a cool Python application](http://github.com/eliezerb/FruitClassification) that performs Oranges vs Apples classification using LDA. | <img src="cvFruitClassification/screenshot.jpg" width="200"/> |
| 11 | +**cvQtImage** | C++/OpenCV/Qt example that displays an image and the RGB values of a pixel based on mouse coordinates. | <img src="cvQtImage/screenshot.jpg" width="200"/> |
| 12 | +**cvQtCameraGL** | An interesting demo that shows how to use C++/OpenCV to retrieve frames from the camera and draw them with Qt `QGLWidget` for GPU rendering (OpenGL). | <img src="cvQtCameraGL/screenshot.gif" width="200"/> |
| 13 | +**cvQtVideo** | Another C++/OpenCV/Qt example on how to display video files with configurable Aspect Ratio. | <img src="cvQtVideo/screenshot.gif" width="200"/> |
| 14 | +**cvWatershedSegmentation** | [Stackoverflow answer](https://stackoverflow.com/a/25851951/176769) that uses C++/OpenCV's watershed segmentation with distance transform to segment beans. | <img src="cvWatershedSegmentation/screenshot.jpg" width="200"/> |
| 15 | +**ipcQtGesture** | C++/Qt application that uses the old *Intel® Perceptual Computing SDK 2013* for gesture recognition. Windows only. | No image available |
