The stereoscopic analysis and depth map creation
European Journal of Business Science and Technology, 2016 This contribution is focused on the use of the stereoscopic image for the purpose of depth map creation. Further, methods for calibration of the camera(s) are discussed. A stereoscopic head was constructed for the purpose of creating a stereoscopic image.

Photon counting compressive depth mapping
Optics Express, 2013 We demonstrate a compressed sensing, photon counting lidar system based on the single-pixel camera. Our technique recovers both depth and intensity maps from a single under-sampled set of incoherent, linear projections of a scene of interest at ultra-low light levels around 0.5 picowatts.

Cascaded Multi-Task Learning of Head Segmentation and Density Regression for RGBD Crowd Counting
IEEE Access, 2020 In this paper we propose a novel regression based RGBD crowd counting method. Compared with previous RGBD crowd counting methods which mainly exploit depth cue to facilitate person/head detection, our approach adopts density map regression and is more ...

Multiple Cylinder Extraction from Organized Point Clouds
Sensors, 2021 Most man-made objects are composed of a few basic geometric primitives (GPs) such as spheres, cylinders, planes, ellipsoids, or cones. Thus, the object recognition problem can be considered as one of geometric primitives extraction.

Depth map upsampling using depth local features
Electronics Letters, 2014 A depth map upsampling method using depth local features is proposed. Depth discontinuity and depth variance are extracted from a low‐resolution depth map and a colour image as the depth local features. They are incorporated into an energy function for the Markov random field (MRF)‐based depth upsampling.
