Kinect Experiments – Distance Filter

Posted on by

Some more interesting experiments with Processing / SimpleOpenNI / Kinect.

The Distance Filter only shows objects within a distance range, for instance all objects that are between 100 cm and 200 cm away from the Kinect.

It can be used as a different way for green (blue) screen techniques and background subtraction techniques.

For determining the distance per pixel the kinect.depthMap is used.
