3D Face Recognition: How to make a fast and reliable database and compare the database with 2D+3D facial input?

A 3D face recognition algorithm has been developed for the Microsoft Kinect during the final bachelor project at Delft University of Technology in 2013. The aim of the project is to develop a prototype face recognition system. The prototype system has to outperform the existing 2D face recognition system. The main goal is to develop a 3D face...

Face Recognition for Cognitive Robots

In the near future the elderly population will increase in size up to a point that there are not enough people to provide support. One solution would be developing service robots, that can perform household tasks and in that way allow elderly to live longer independently. These service robots have to be able to adapt to changing environments,...

Face Recognition System

In this thesis a research about a face recognition system is presented. The system uses a database of images to identify individuals. The starting point is a huge database of “known faces”, the FERET database. If a new face is presented the system has to decide whether this face is a member of the database or not. The matching of a face can be...

Seismic behaviors of earth-core, concrete-faced-rock-fill, and composite dams

The investigation on the seismic behavior of dams becomes crucial but is limited due to lack of experimental or field data. This paper aims to experimentally simulate the seismic behavior of three types of dams; earth-core rock-fill dam (ECRD), concrete-faced rock-fill dam (CFRD), and composite dam which combines concrete dam and CFRD. A series...

Tracking facial micro-features using an ensemble of particle filters

In this work we propose a template-based tracker for simultaneously tracking multiple targets such as facial features. Our work falls within the particle fil- tering framework and more specifically it extends the Particle Filtering with Factorized Likelihoods (PFFL) tracking scheme. In this work we introduce the idea of using a distribution per...

Real Time Eye Blink Detection using a Configurable Processor

This thesis describes the approach to create a real time eye blink detector using a new perception processor. Tried is to describe how the processor works and to find out possible fields of application. Supposed strength of the processor is it's speed combined with the possibility of changing the configuration at run time. Since the current...

Adaptive image interrogation for PIV: Application to compressible flows and interfaces

As an experimental tool, Particle Image Velocimetry has quickly superseded traditional point-wise measurements. The inherent image processing has become standardized though the performances are strongly dependent on user experience. Moreover, the arduously selected image interrogation parameters are applied uniformly throughout the image...

Sign Language Recognition by Combining Statistical DTW and Independent Classification

To recognize speech, handwriting, or sign language, many hybrid approaches have been proposed that combine Dynamic Time Warping (DTW) or Hidden Markov Models (HMMs) with discriminative classifiers. However, all methods rely directly on the likelihood models of DTW/HMM. We hypothesize that time warping and classification should be separated...

Dialog detection in narrative video by shot and face analysis

The proliferation of captured personal and broadcast content in personal consumer archives necessitates comfortable access to stored audiovisual content. Intuitive retrieval and navigation solutions require however a semantic level that cannot be reached by generic multimedia content analysis alone. A fusion with film grammar rules can help to...

Implementation and testing of variable scale topological data structures: Experiences with the GAP-face tree and GAP-edge forest

With the increase of the availability of large-scale geographic data set and the rise of widespread computer networks, such as the Internet, the need has arisen to be ableto transfer this data by means of these networks. The networks form the basis for a Geographic Information Infrastructure (GII), in which data users, data providers and data...

Rock and roll: Turbulence-induced damage to granular bed protections

Layers of stone or rock are often applied around hydraulic structures to protect the sand bed from scouring. Determining the size of the rocks is complicated by the fact that the flow over a bed protection usually is non-uniform. This thesis describes two experimental series in which the stability of a single stone under non-uniform flows is...

Integrated field equations methods for the computation of electromagnetic fields in strongly inhomogeneous media

Electromagnetic field theory plays a very important role in present-day technology; examples of technologies based on electromagnetism that are inextricably bound up with every day life are: radar, remote sensing, geoelectromagnetics, bioelectromagnetics, antennas, wireless communication, optics, high-frequency circuits, and so on. In order to...

Steenstabiliteit in een turbulente stroming achter een afstap

Het onderwerp van deze studie is een niet-uniforme stroming waarin sprake is van een plaatselijk verhoogde aanval op het bodemmateriaal door de lokaal hogere turbulentie. In een 15 m lange stroomgoot met een breedte van 40 cm is door middel van een backward-facing step ofwel afstap een niet-uniforme stroming gecreeerd. Om de schade aan de...

Hoofdstroming contra menglaag: De invloed van een menglaag op het begin van bewegen van bodemmateriaal

Experimental research on the stability of bed material behind a backward facing step. Measured is the stability as a function of the local velocity and the local turbulence (turbulence intensity) due to the eddy formation.

Dynamic forces on a bed element in open channel flow with a backward facing step

Experiments to measure forces on objects in open channel flow behind a bacward facing step

Coarsening and solutioning of precipitates in superalloys

Coarsening and solutioning of the main strengthening phase for the majority of superalloys, the y' phase, are discussed. It is shown that a general prediction of coarsening rates and solutioning temperatures is possible.

TEM "in situ" straining and bulk studies of the selection of glide systems in f.c.c. single crystals

Plastic deformation of f.c.c. single crystals was studied by means of straining experiments inside a transmission electron microscope on Cu foils and some related bulk straining experiments on Cu and Al single crystals. In the foils and bulk crystals with the same orientation of the normal to the large face the same non-primary glide...

Investigation of excess water-pressure under the asphalt facing of sand-cored dykes: Paper for 9the Conference of the International Association of Hydro-Environment Engineering and Research, Belgrade, 1961

The excess pressures anticipated underneath the asphalt facing of a number of sea dykes were determined with the aid of plate-shaped electrical conductors and alternating current. As these excess pressures are influenced by factors varying from place to place in the prototype, a series of tests were carried out in which one or more of these...
