Depth information from image sequences using two-dimensional cepstrum
… less demanding and yields more accurate depth information than the existing methods. One of the traditional techniques for extracting depth information is to find the disparities of corresponding points in stereo images following a biological model of 3-D vision. A normal binocular stereo …

Human detection and action recognition using depth information by Kinect
Traditional computer vision algorithms depend on information taken by visible-light cameras. But there are inherent limitations of this data source, e.g. they are sensitive to illumination changes, occlusions and background clutter. Range sensors give us 3D structural information of the scene and …

Captured open book image de-warping and shading correction using 3D depth information
… of an open book in captured images using of depth information. This work is relevant to camera-based capture devices that can use a projector to cast structured light patterns to provide depth information. In order to improve the visual quality of captured documents, we established our …

Improving the Perception of Depth of Image-Based Objects in a Virtual Environment
… technique to capture, represent, and render depth information in the context of 3D IBR. We tested the value of displacement by displacement map, shading by normal, and image angle interval with our technique. We ran an online user study of 60 participants to evaluate the value of adding depth …

3D Sketch Recognition Using The Microsoft Kinect
… any studies on the performance of incorporating depth information into a sketch. The motivation behind this project is to develop software that will allow a user to draw in a three-dimensional space, incorporating this information, as well as determining whether this depth information will result …

Depth Correction++ for pseudo-LiDAR
… detection. 3D object detection can provide more information from the 3D bounding boxes, compared to 2D bounding boxes, which can better describe surrounding obstacles with details, providing further help with route planning of autonomous vehicles. Researchers commonly use LiDAR data in 3D object …

Automatic Positioning and Design of a Variable Baseline Stereo Boom
… rely on two spatially fixed cameras to gather depth information about a scene. The cameras typically have a fixed distance between them, known as the baseline. As the baseline increases, the estimated 3D information becomes more accurate, which makes it advantageous to have as large a baseline …

Disjunctions and convergences: a study of stakeholders' perceptions of public participation in service delivery in Cape Town's Blikkiesdorp
… on a single case study in order to gain in-depth information about key stakeholder perceptions.

Development of a human fall detection system based on depth maps
… risk factors and position of the subject using depth information from Microsoft Kinect sensor. Classification of human fall from other activities of daily life is accomplished using height and velocity of the subject extracted from the depth information after considering the fall risk level of …

A Novel Inpainting Framework for Virtual View Synthesis
… usually involves transmitting both textural and depth information captured from different viewpoints to the receiver, to enable the synthesis of an arbitrary view. In rendering these virtual views, perceptual holes can appear due to certain regions, hidden in the original view by a closer object, …

Effects of depth cues on depth judgements using a field-sequential stereoscopic CRT display
Current interest in three-dimensional (3-D) information displays has focused on the use of field-sequential CRT techniques to present binocular stereoscopic images. Although it is widely believed that stereopsis provides a potent depth information cue, numerous monocular cues exist which may …

Deep learning-based optimization of light field processing
… rays’ capacity and density present challenges in information storage and transmission. Moreover, traditional display technology is limited in its ability to depict directional and depth information, and current light field display technology is inferior to high-definition displays. Therefore, in …

Learning Sim-to-Real Robot Parkour from RGB Images
… These successes are largely attributed to depth-based visual locomotion policies, known for their robust transferability between simulated and real-world environments (sim-to-real). However, depth information inherently lacks the semantic information present in RGB images. This thesis …
