ABSTRACT
Depth video cameras are starting to play a major role in videogames and novel Natural User Interface systems, which represent an interesting challenge to the computer vision field.
This kind of video sensors typically uses the signal reflected by an IR light to measure the total distance from the object to the camera. At some parts of the scene the distance can’t be estimated and, therefore, the depth image will be severely affected by noise. These failures occur most frequently in surfaces that don’t reflect the IR light, and the signal quality deteriorates as the distance increases.
