    Abstract: In general, techniques are described that facilitate processing of a depth map image in mobile devices. A mobile device comprising a depth camera, a camera and a processor may be configured to perform various aspects of the techniques. The depth camera may be configured to capture a depth map image of a scene. The camera may include a linear polarization unit configured to linearly polarize light entering into the camera. The camera may be configured to rotate the linearly polarization unit during capture of the scene to generate a sequence of linearly polarized images of the scene having different polarization orientations. The processor may be configured to perform image registration with respect to the sequence of linearly polarized images to generate a sequence of aligned linearly polarized images, and generate an enhanced depth map image based on the depth map image and the sequence of aligned linearly polarized images.

    Abstract: A structured light three-dimensional (3D) depth map based on content filtering is disclosed. In a particular embodiment, a method includes receiving, at a receiver device, image data that corresponds to a structured light image. The method further includes processing the image data to decode depth information based on a pattern of projected coded light. The depth information corresponds to a depth map. The method also includes performing one or more filtering operations on the image data. An output of the one or more filtering operations includes filtered image data. The method further includes performing a comparison of the depth information to the filtered image data and modifying the depth information based on the comparison to generate a modified depth map.

    Abstract: Systems and method for generating depth maps using active sensing technology, for scenes with moving objects, is disclosed. One aspect provides for a method that includes estimating areas in adjacent frames that correspond to a moving object by generating a probability map for each received frame, the probability map comprising a probability value at each pixel. The method also includes computing a convex temporal average map using a plurality of the reflected structured light frames including at least the prior frame received at time t−1, the received frame received at time t, and the next frame received at time t+1, the value at each pixel of the convex temporal average map weighted and normalized by the probability map at each pixel at each time. The method also includes determining the codewords at each pixel in the convex temporal average map, and generating a depth map from the determined codewords.
