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.
