Configurator

The Configurator is a piece of software for adjusting the parameters of the filters used by touchd during run time. Using the Configurator the developer does not need to stop touchd, change the filter settings and restart touchd again to verify the settings. The Configurator provides an easy to use interface with the following options to manipulate the filter settings:

• c activates/deactivates the Configurator. While active the current filter settings are displayed. Switching filters is still possible using the number key of the keyboard
• h shows/hides the help
• TAB the tabulator key is used for switching between the different filter options
• i is used to increase the selected value by steps of one
• d is used to decrease the selected value by steps of one
• e switches to edit mode: in this mode the user can enter a numerical value to overwrite the current selected one. The confirm the input Enter needs to be pressed. The user can leave the edit mode by pressing e again without saving the changes.

Using the Area Filter there are two additional keys used:

• space reset all filters
• r reset current filter

In the Background Subtraction Filter (BGSubFilter):

• r reset the background image that is subtracted from each frame captured

If working with a Microsoft Kinect:

• m toggle between depth image and RGB image. Both images are registered to each other using a default matrix. Since IR cam and RGB cam are stationary in the Kinect device, registration has to be performed once. Default matrix is well suited.
