Sampling in Computational Cameras
… image signal processing (ISP) in digital cameras and show that AI has significantly improved the performance of ISP functions, such as demosaicing, denoising, and white balance. We than demonstrate a deep-learning (DL)-based image signal processor that regroups the ISP functions and …

Vibration Extraction Using Rolling Shutter Cameras
… been applied to solve this problem, high speed cameras are usually preferred. This study employs a consumer level rolling shutter camera for extracting main frequency components of small vibrations. A rolling shutter camera exposes continuously over time on the vertical direction of the sensor, …

How To Do Things With Cameras
… and the title of my thesis How To Do Things With Cameras reflects this performative investigation. I go on to examine how the performative use of the camera impacts on a live mode of address and, through considering work by artists including Vito Acconci and John Baldessari,how this must stretch …

Accidental cameras : creating images from shadows
In this thesis, we explore new imaging systems that arise from everyday occlusions and shadows. By modeling the structured shadows created by various occlusions, we are able to recover hidden scenes. We explore three such imaging systems. In the first, we use a wall corner to recover …

General linear cameras : theory and applications
… (including pushbroom and two-slit) cameras, as well as epipolar plane images. It also includes three new and previously unexplored multiperspective linear cameras. The GLC model is general and linear in the sense that, given any vector space where rays are represented as points, it …

Obstacle and Change Detection Using RGB Cameras
… is to implement this dual approach using RGB cameras and threadpooling for higher efficiency, speed, and resource usage, ensuring robustness against environmental factor variations to detect test image paths for obstacles and changes. In geometric based approach, features are extracted using …

University student perceptions of body-worn cameras
… this study examined the perceptions of body-worn cameras held by university students. Demographic and educational characteristics, as well as individual level experiences, were measured for to determine their relationship with student perceptions. Findings indicated that respondents held positive …

Object Detection and Tracking Using Uncalibrated Cameras
… measurements obtained from multiple uncalibrated cameras. A general approach to track the location of a target involves different phases including calibrating the camera, detecting the object's feature points over frames, tracking the object over frames and analyzing object's motion and behavior. …

Applications of RGB-D Cameras in Healthcare
RGB-D cameras are a type of imaging device that includes a standard colour camera and a depth sensor. The depth sensor records depth images, where each pixel measures the distance of the target from the camera. Using data from the RGB-D camera, we can recon- struct a three-dimensional scene. Since …

Stereo vision and mapping with unsynchronized cameras
… systems by tolerating unsynchronized stereo cameras. Results indicate that synchronization allows the system to locate points significantly more accurately than the system without synchronization. When compared with a monocular mapping system, synchronized stereo provides a more detailed map …

Efficient volumetric reconstruction from multiple calibrated cameras
The automatic reconstruction of large scale 3-D models from real images is of significant value to the field of computer vision in the understanding of images. As a consequence, many techniques have emerged to perform scene reconstruction from calibrated images where the position and orientation of …

Body-relative navigation guidance using uncalibrated cameras
… focused on metric methods based on calibrated cameras, the work presented in this thesis demonstrates a novel approach to navigation using uncalibrated cameras. During the first visit of the environment, the method builds a topological representation of the user's exploration path, which we …

Micro cameras as adjunct tools in biomedical applications
… the miniaturisation of CMOS image sensors, micro-cameras are being investigated for use in biomedical imaging and the development of biomedically specific sensors has begun. This thesis makes several important contributions to the use of these micro-cameras as adjunct tools that meet a number of …

Aircraft state estimation using cameras and passive radar
Multiple target tracking (MTT) is a fundamental task in many application domains. It is a difficult problem to solve in general, so applications make use of domain specific and problem-specific knowledge to approach the problem by solving subtasks separately. This work puts forward a MTT framework …

Transit timing with fast cameras on large telescopes
Timing and system parameters were measured for seven transiting exoplanets: OGLETR- 56b (11 transits), OGLE-TR-132b (7), OGLE-TR-111b (6), OGLE-TR-113b (6), CoRoT-2b (3), OGLE-TR-10b (3), and XO-2b (2). Ground-based observations of 38 transits were made using three new frame-transfer instruments: …
