Abstract: In accordance with disclosed embodiments, there are provided systems, methods, and apparatuses for implementing maximum likelihood image binarization in a coded light range camera. For instance, a depth camera is described having therein a projector to project a collection of planes, each at a different angle of projection, onto a scene via a plurality of coded pattern images, each of the coded pattern images having encoded therein via a plurality of stripes, the angle of projection for the plane of projection within which the respective coded pattern image is projected; a detector to capture the plurality of coded pattern images from the scene; a processing component to output a bit value for each pixel in the captured plurality of coded pattern images based on the pixel captured and based further on a patch of neighboring pixels surrounding the pixel; a decoder to decode each of the plurality of coded pattern images based on the bit values output by the processing component to determine the angle of projection for the corresponding plane of projection; and a triangulator to determine a position of an object in the scene based on an intersection of the determined angle of projection for the corresponding plane of projection with a geometric ray originating from the detector that detected the plurality of the coded pattern images. Other related embodiments are disclosed.

Abstract: Various embodiments are generally directed to an apparatus, method, system, and/or other techniques to determine estimated ambient electromagnetic (EM) radiation information based at least partially on ambient recovery sensor measurement information, determine estimated albedo information based at least partially on albedo recovery sensor measurement information, albedo recovery emitter modulation information, sensing matrix information, and the estimated ambient EM radiation information, and determine estimated range information based at least partially on range recovery sensor measurement information, the estimated albedo information, range recovery emitter modulation information, and sensing matrix information.
