Abstract: A depth estimation system is described capable of determining depth information using two images from two cameras. A first camera captures a first image and a second camera captures a second image, both images including a plurality of light channels. A scan direction is selected from a plurality of scan directions. For the selected scan direction, along each of a plurality of scanlines, the system compares pixels from the first image to pixels from the second image. The comparison is based on calculating a census transform for each pixel in the first image and a census transform for each pixel in the second image. This comparison is used to determine a stereo correspondence between the pixels in the first image and the pixels in the second image. The system generates a depth map based on the stereo correspondence.

Abstract: Bordering pixels delineating a texture hole region are identified in a target image. Depth values of the bordering pixels are automatically clustered into two depth value clusters. A specific estimation direction is selected from multiple candidate estimation directions for a texture hole pixel in a texture hole region. A depth value of the texture hole pixel is estimated by interpolating depth values of two bordering background pixels in the specific estimation direction. The estimated depth value is used to warp the texture hole pixel into a reference view represented by a temporal reference image. A pixel value of the texture hole pixel is predicted based on a reference pixel value of a reference pixel from the reference image to which the texture hole pixel is warped using the estimated depth value.

Abstract: Described herein are systems for generating 3D models using imaging data obtained using an array of light projectors, at least one object boundary detector, and a robotic member with an end effector. A first point cloud of data for an object may be generated based on boundary information obtained by the object boundary detector(s). Dimensions for the object may be determined based on the first point cloud of data. A second point cloud of data may be generated based on the dimensions for the object and a configuration of light projectors where the second point cloud corresponds to potential coordinates for a location where the robotic member and end effector can be positioned along a path around the object to capture the image data of the object. A path may be generated to avoid collision between the object and the robotic member or end effector while optimizing the number of capture location points within the second point cloud of data.

Abstract: It is proposed a Method and System for Global Motion Estimation and Compensation. The system operates on two depth maps which contain a reference depth map and a current depth map as well as their associated texture images if available. The system executes four major steps which are feature detection (step 1), global motion compensation (GMC) (step 2), major moving objects (MMO) detection and the estimation of their motion parameters denoted as major motion parameters (MMPs) (step 3), and local motion compensation (LMC) of macroblocks or other coding/prediction units (step 4). The output of the system is the global motion parameters (GMPs), major moving objects (MMOs) and MMPs, the local motion vectors (LMVs), and the coding modes.

Abstract: Described herein are a system and methods for generating 3D models using imaging data obtained from an array of camera devices. In embodiments, a stochastic shape distribution may be applied upon an object to be modeled in invisible ink. The system activates a first lighting mode which causes the stochastic shape distribution to be visible and captures a first set of images that depict the stochastic shape distribution on the object. The system then activates a second lighting mode that causes the stochastic shape distribution to be hidden and captures images of the object as it would normally appear (without the stochastic shape distribution). The images having the stochastic shape distribution may be used to determine alignment information for the images within the set of images. That alignment information may then be attributed to the second set of images and used to generate the 3D model.
