20140015992 | Specular Edge Extraction Using Multi-Flash Imaging - A method and system extract features from an image acquired of an object with a specular surface by first acquiring an image while illuminating the object with a hue circle generated by a set of lights flashed simultaneously. The lights have different colors and are arranged circularly around a lens of a camera. Then, the features correspond to locations of pixels in the image within a neighborhood of pixels that includes a subset of the colors of the lights. | 01-16-2014 |
20140016862 | Method and Apparatus for Extracting Depth Edges from Images Acquired of Scenes by Cameras with Ring Flashes Forming Hue Circles - A set of images is acquired of a scene while illuminating the scene with a set of colors with different hues. The set of colors is generated by a set of light sources arranged in a substantial circular manner around a lens of a camera to form a hue circle, wherein each light source emits a different color. A shadow confidence map is generated from the set of images by using hues and saturations of pixels in the set of images. Then, depth edges are extracted from the shadow confidence map. | 01-16-2014 |
20140037136 | Method and System for Determining Poses of Vehicle-Mounted Cameras for In-Road Obstacle Detection - Poses of a movable camera relative to an environment are obtained by determining point correspondences from a set of initial images and then applying 2-point motion estimation to the point correspondences to determine a set of initial poses of the camera. A point cloud is generated from the set of initial poses and the point correspondences. Then, for each next image, the point correspondences and corresponding poses are determined, while updating the point cloud. | 02-06-2014 |
20140037146 | Method and System for Generating Structured Light with Spatio-Temporal Patterns for 3D Scene Reconstruction - A structured light pattern including a set of patterns in a sequence is generated by initializing a base pattern. The base pattern includes a sequence of colored stripes such that each subsequence of the colored stripes is unique for a particular size of the subsequence. The base pattern is shifted hierarchically, spatially and temporally a predetermined number of times to generate the set of patterns, wherein each pattern is different spatially and temporally. A unique location of each pixel in a set of images acquired of a scene is determined, while projecting the set of patterns onto the scene, wherein there is one image for each pattern. | 02-06-2014 |
20140219547 | Method for Increasing Resolutions of Depth Images - A resolution of a low resolution depth image is increased by applying joint geodesic upsampling to a high resolution image to obtain a geodesic distance map. Depths in the low resolution depth image are interpolated using the geodesic distance map to obtain a high resolution depth image. The high resolution image can be a gray scale or color image, or a binary boundary map. The low resolution depth image can be acquired by any type of depth sensor. | 08-07-2014 |
20140333615 | Method For Reconstructing 3D Scenes From 2D Images - A method reconstructs at three-dimensional (3D) real-world scene from a single two-dimensional (2D) image by identifying junctions satisfying geometric constraint of the scene based on intersecting lines, vanishing points, and vanishing lines that are orthogonal to each other. Possible layouts of the scene are generated by sampling the 2D image according to the junctions. Then, an energy function is maximized to select an optimal layout from the possible layouts. The energy function use's a conditional random field (CRF) model to evaluate the possible layouts. | 11-13-2014 |
