The signal-to-noise ratio of modern cameras under normal operating conditions tends to be limited by “photon noise” originating from the random arrival photons. For best ratio, it is desirable collect as much light possible, and avoid losses internally in camera. There currently no widely accepted metric for resulting net collection, which depends on many aspects camera design. IEEE Standards A...

Light field photography has gained a significant research interest in the last two decades; today, commercial light field cameras are widely available. Nevertheless, most existing acquisition approaches either multiplex a low-resolution light field into a single 2D sensor image or require multiple photographs to be taken for acquiring a high-resolution light field. We propose a compressive ligh...

This work presents a procedure for refining depth maps acquired using RGB-D (depth) cameras. With numerous new structured-light RGB-D cameras, acquiring high-resolution depth maps has become easy. However, there are problems such as undesired occlusion, inaccurate depth values, and temporal variation of pixel values when using these cameras. In this paper, a proposed method based on an exemplar...

Single plane illumination microscopy based fluorescence correlation spectroscopy (SPIM-FCS) is a new method for imaging FCS in 3D samples, providing diffusion coefficients, transport, flow velocities and concentrations in an imaging mode. SPIM-FCS records correlation functions over a whole plane in a sample, which requires array detectors for recording the fluorescence signal. Several types of ...

With just a few notable exceptions, research supports the concept that red light cameras (RLCs) improve safety. However, many communities that have implemented RLC programs have faced a firestorm of public opinion associated with the use of RLCS, with many communities having to remove the cameras. What makes or breaks a red light camera program? Because of the experimental design process, state...

Vision is an extremely important sense for both humans and robots, providing detailed information about the environment. In the past few years, the use of digital cameras in robotic applications has been significantly increasing. The use of digital cameras as the main sensor allows the robot to capture the relevant information of the surrounding environment and take decisions. A robust vision s...

Modern smartphones provide a high sophisticated camera and a high resolution display. Therefore, they can be used to enable various application scenarios for 1D and 2D barcode recognition as well as barcode presentation device. The device positioning against the barcode allows innovative interaction: e.g., additional product information or “rail information” on paper tickets. In the future, the...

Intelligent Transportation Systems(ITS) have been introduced to give solutions for traffic problems such as traffic accidents and congestions. Assistance of safe driving is one of the major significant area in ITS. On-vehicle and Infrastructure cameras play an important role in many ITS deployments related to assistance for safe driving. Those systems detect vehicle local information by cameras...

Marine current energy converters such as tidal and riverine turbines have the potential to provide reliable, clean power. The risk of collision fishes with marine is not yet well understood, in part due challenges associated observing fish at turbine sites. Turbidity light availability can limit effectiveness optical sensors like video cameras, motivating use acoustic cameras for this task. How...
