This app uses the BackgroundSubtractorMOG algorithm from OpenCV's android library to identify objects in motion from the camera and draws a red overlay around/over them. The ideal is to have nice contours drawn around the objects that are moving. A slider is also added for the user to adjust the learning rate, which may or may not have any effect on the contours.
In order to utilize the app, the latest version of OpenCV Manager (also found on Google Play) must be downloaded and installed correctly. This app has been successfully tested on Android 2.3.4 and Android 4.3.
At the moment this can considered an initial tech demo, please feel free to play around with it. The source code for this implementation can also be found in github link below!
For ideal WiFi/WLAN connectivity, please look for the latest firmware version at Fischertechnik homepage and update your TXT Controller.
To control the “old” ROBO TX Controller, please have a look at the RoboTXdroid App.
A corresponding example program file that can be adopted to anybody's purposes including documentation is available on the Fischertechnik homepage: http://www.fischertechnik.de/ResourceImage.aspx?raid=7715
