Abstract: A mechanism is described for facilitating three-dimensional (3D) depth imaging systems, and morphological and geometric filters for edge enhancement in depth images at computing devices according to one embodiment. A method of embodiments, as described herein, includes detecting an input digital image of an object, the digital image comprising data pixels contaminated by noise and confidence values corresponding to the data pixels, and computing a morphological filter by matching the confidence pixels in the input digital image with a set of matching templates, and using a set of masking templates to determine the data pixels and confidence pixels in the filtered image. The method further include computing an edge filter by performing computation of distances between the data pixels along a plurality of directions to determine an edge direction, and determining the data pixels and and the confidence pixels in a filtered image based on the edge direction. The method may further include applying at least one of the morphological filter and the edge filter to filter the digital image.

Abstract: A mechanism is described for facilitating code filters for coded light depth acquisition in depth images at computing devices according to one embodiment. A method of embodiments, as described herein, includes detecting a code image of an object comprising pixels of code values and pixels of metadata values including confidence and code transition locations, and computing a vertical filter to be applied to the code image to smooth out the code transitions along vertical directions. The method further include computing a horizontal filter to be applied to the code image to smooth out the code transitions along horizontal directions, and computing a consistency filter to be applied to the code image to increase an accuracy of the code values and mark inconsistent pixels as invalid. The method may further include applying at least one of one or more of the vertical filter, the horizontal filter, and the consistency filter to filter the digital image, and outputting the filtered code image comprising filtered code values and filtered metadata values.

Abstract: Example range estimation apparatus disclosed herein include a first signal processor to estimate a signal power parameter and a noise power parameter of a LIDAR system based on first data to be output from a light capturing device of the LIDAR system. Disclosed example range estimation apparatus also include a second signal processor to generate templates corresponding to different possible propagation delays associated with second data to be output from the light capturing device, the second data associated with a modulated light beam projected by the LIDAR system, the templates generated based on the signal power parameter and the noise power parameter, and the second data to have a higher sampling rate and a lower quantization resolution than the first data. In some examples, the second signal processor is also to determine, based on the templates, an estimated propagation delay associated with the second data.

Abstract: Example range estimation apparatus disclosed herein include a first signal processor to process first data output from a light capturing device of a LIDAR system to estimate signal and noise power parameters of the LIDAR system. Disclosed example range estimation apparatus also include a second signal processor to generate templates corresponding to different possible propagation delays associated with second data output from the light capturing device while a modulated light beam is projected by the LIDAR system, the templates generated based on the signal and noise power parameters, and the second data having a higher sampling rate and a lower quantization resolution than the first data. In some examples, the second signal processor also cross-correlates the templates with the second data to determine an estimated propagation delay associated with the second data, the estimated propagation delay convertible to an estimated range to an object that reflected the modulated light beam.
