When this value is
true (the default), the capture output smooths noise and fills in missing or invalid values (caused by low light or lens occlusion) in depth data maps by temporally interpolating between previous and subsequent frames of captured depth data.
Filtering depth data makes it more useful for applying visual effects to a companion image, but alters the data such that it may no longer be suitable for computer vision tasks. (In an unfiltered depth map, missing values are represented as
