Claim 0:
1. A computing system, comprising:
a logic machine; and
a storage machine holding instructions executable by the logic machine to process depth data by
obtaining depth image data and active brightness image data for a plurality of pixels, the depth image data comprising phase data for a plurality of frequencies,
identifying low-signal pixels based at least on the active brightness image data,
applying a spatial denoising filter to phase data of the low-signal pixels to obtain denoised phase data and not applying the spatial denoising filter to phase data of other pixels,
after applying the spatial denoising filter, performing phase unwrapping on the phase data for the plurality of frequencies to obtain a depth image, and
outputting the depth image.
