In this paper, we address the problem of people detection and tracking in crowded scenes using range cameras. We propose a new method for people detection and localisation based on the combination of background modelling and template matching. The method uses an adaptive background model in the range …

Earth’s magnetic field, also known as the geomagnetic field, interacts with the solar wind, a stream of charged particles originating from the Sun. The interaction causes the geomagnetic field to undergo variations, called geomagnetic disturbances or geomagnetic activity. This bachelor thesis features …

The purpose of this report is to assess the relevance of the measurement of the spectrally resolved distribution of radiation in tokamak boundary plasmas. This assessment is important and urgent in view of the recent ambition to design and construct a multi-camera configuration for hyper imaging spectroscopy1 …

Increasing oil and energy demand asks for higher efficiency when it comes to oil recovery. To increase oil recovery efficiency, pore-scale mechanisms during waterflooding, a common recovery method, have to be better understood. This provides knowledge on the dynamic process during imbibition, which …

In this study, we recorded sound and behaviour from dairy cows by audio and video recordings. Four cameras and microphones were placed in a modern dairy farm in Herwijnen, The Netherlands. Three cameras and microphones recorded dairy cows, one camera and microphone recorded heifers between four and ten …

Axon Digital Design develops modular systems and equipment for audio and video signal processing and monitoring, mainly aimed at the broadcasting industry. The recent successes of 3D film productions have pushed the consumer TV market into a new era: 3D television in the living room. One fundamental …

Technology is becoming omnipresent in public spaces: from CCTV cameras to smart phones, and from large public displays to RFID enabled travel cards. Although such technology comes with great potential, it also comes with apparent (privacy) threats and acceptance issues. Our research focuses on realizing …

People counting is a challenging task with many applications. We propose a method with a fixed stereo camera that is based on projecting a template onto the depth image. The method was tested on a challenging outdoor dataset with good results and runs in real time.

The use of cameras is growing: not only personal computers and laptops are standard equipped with a camera, but also the public domain is increasingly equipped with cameras. Today's camera is not merely a pair of eyes. A surveillance camera can see much more than a single person can do. The rapid proliferation …

In this paper we propose a head detection method using range data from a stereo camera. The method is based on a technique that has been introduced in the domain of voxel data. For application in stereo cameras, the technique is extended (1) to be applicable to stereo data, and (2) to be robust with …
