Abstract: Systems and techniques are described herein for improved feature correlation. For instance, an apparatus for improved featured correlation is provided. The method may include a projector configured to project a pattern into a scene for feature correlation by an imaging device that captures images of the pattern as projected into the scene; wherein the apparatus is separate from the imaging device.

Abstract: Systems and techniques are provided for wireless communication. For example, a process can include obtaining a first image of an environment, the first image including a pattern of light. The process can further include determining a pixel window for a pixel of the first image; determining a set of transform pixels based on the pattern of light, wherein the set of transform pixels are a subset of pixels from the pixel window; performing a census transform based on the pixel and the set of transform pixels to obtain census transform information for the first image; and generating depth data based on the census transform information for the first image and census transform information for a second image.
