Surface projection for mixed pixel restoration [PDF]

open access: yes2009 24th International Conference Image and Vision Computing New Zealand, 2009
Amplitude modulated full-field range-imagers are measurement devices that determine the range to an object simultaneously for each pixel in the scene, but due to the nature of this operation, they commonly suffer from the significant problem of mixed pixels.
