Parameters having significant impact on FRS matching

Facial Recognition Systems är något som har blivit populärt de senaste åren, speciellt efter den 11 september 2001. Möjligheten att kunna över-vaka personer som rör sig i olika miljöer har varit av intresse för bland annat regeringar, till exempel USA:s regering. Eftersom det finns mängder med olika typer av undersökningar och alla försöker göra så bra matchningar som möjligt av personer mot databaser, fast de utförs på olika sätt, är det intressant att se om det finns någon parameter som har en större påverkan på resultaten, oavsett om undersökningen görs med 2D, 3D eller en kombination av metoderna. Det finns många olika faktorer och parametrar som påverkar matchningsprocenten därför skall denna littera-turstudie försöka lokalisera och se om det finns någon parameter som har en större påverkan på matchningsprocenten. Det visar sig att två parametrar har en större påverkan än övriga parametrar.

Support Vector Machines for Classification applied to Facial Expression Analysis and Remote Sensing

The subject of this thesis is the application of Support Vector Machines on two totally different applications, facial expressions recognition and remote sensing.The basic idea of kernel algorithms is to transpose input data in a higher dimensional space, the feature space, in which linear operations on the data can be processed more easily. These operations in the feature space can be expressed in terms of input data thanks to the kernel functions. Support Vector Machines is a classifier using this kernel method by computing, in the feature space and on basis of examples of the different classes, hyperplanes that separate the classes. The hyperplanes in the feature space correspond to non linear surfaces in the input space.Concerning facial expressions, the aim is to train and test a classifier able to recognise, on basis of some pictures of faces, which emotion (among these six ones: anger, disgust, fear, joy, sad, and surprise) that is expressed by the person in the picture. In this application, each picture has to be seen has a point in an N-dimensional space where N is the number of pixels in the image.The second application is the detection of camouflage nets hidden in vegetation using a hyperspectral image taken by an aircraft.

Kroppsliga uttryck genom gestik och mimik i kommunikation med barn.

The aim of the study is to investigate how pedagogues working with gesticulation and facial expressions to communicate with children aged 3-5 years. The methods used are observations as well as interviews of educators. My empricial evidence was collected on two different preschools in Värmland County. The pedagogues are dealing with body language in a conscious way by collections as they sing and they reinforce feelings of characters support. In my conclusion I have come come to the conclusion that there is no difference on how male and female educators use gesticulation and facial expressions without its personality traits and body language often are unconsciously in conversations with children..

Känsloigenkänning i form av ansiktsuttryck med Kinect

Facial expressions are a part of our body language that helps us to clarify the verbal communication between humans. We use our facial expressions every day, both consciously and unconsciously, to express emotions and attitudes depending on the situation. The hypothesis of the study is: Given a facial expression, how well can Microsoft Kinect, as an input method, determine a person?s feelings with the two algorithms Naive Bayes and Sequential Minimal Optimization? The feelings are limited to happy, sad, surprised and disgusted. With the help of Kinect, a person?s facial data, both coordinates of the face and parameterized data, were saved and used for machine learning.

Editing, Streaming and Playing of MPEG-4 Facial Animations

Computer animated faces have found their way into a wide variety of areas. Starting from entertainment like computer games, through television and films to user interfaces using ?talking heads?. Animated faces are also becoming popular in web applications in form of human-like assistants or newsreaders. This thesis presents a few aspects of dealing with human face animations, namely: editing, playing and transmitting such animations.

Reproduktionen ? Validering av reell kompetens och högskolans rådande ordning

This thesis examines the relationship between recognition of prior learning and the aim to increase social and ethnical diversity in higher education. Recognition of prior learning is a result of educational politics aiming to broaden social and ethnical recruitment to higher education. By examining if recognition of prior learning rather can, and shall, be seen as part of what Pierre Bourdieu calls educational social reproduction I try to question whether it fulfils education policy goals or not. My results show that persons responsible for recognition of prior learning rather recognise knowledge from prior educational institutions than knowledge gained outside the educational system. Considering this, recognition of prior learning does not quite live up to the aims.

Fri rörlighet för varor på den inre marknaden och principen om ömsesidigt erkännande

The aim of this thesis is to identify some of the obstacles to trade, that occurs on the common market, and to analyse the errors that still occurs in the national authorities application of the principle of mutual recognition. Is the principle of mutual recognition sufficient for the creation of a common market, or is there a need for additional measures to cope with the obstacles to trade that still exists on the common market? The problems related to the incorrect procedures of the national authorities and the fact that undertakings prefer to bring their products in to line with the rules of every single member state must be solved, if the principle of mutual recognition is to become trustworthy. On some areas, harmonisation ought to be chosen above the principle of mutual recognition, but in other cases an increased administrative collaboration, mandatory training for the national authorities or information campaigns intended mainly for undertakings could be the answer. The possibility to help undertakings to sue member states for damages should also be investigated.

Ansiktsriggning för datorspel med Facial Action Coding System : Hur teorier om ansiktsmuskulatur och uttryck kan appliceras på digitala karaktärer

Det här examensarbetet undersöker om ett anatomiskt system framtaget för att kategorisera ansiktsrörelser inom psykologisk forskning kan anpassas på en ansiktsrigg för att effektivare kunna framställa ansiktsanimation för datorspel. Rapporten beskriver varför Facial Action Coding System skapades, hur det används samt tar upp olika sammanhang som systemet tidigare använts för. Rapporten beskriver det praktiska arbetet för att konstruera en ansiktsrigg ämnat för datorspel och diskuterar skillnader mellan att rigga för datorspel och film. Examensarbetet beskriver klassiska användbarhetsprinciper och vad man bör tänka på när produkten skall bli så användningsbar som möjligt. Ett animationsverktyg baserat på FACS och de ?Action Units? som systemet innehåller har tagits fram för att genomföra undersökningen på animatörerna från min praktikplats på Starbreeze Studios AB.

Brukarorganisationers syn på ICF som arbetsredskap ? och dess betydelse för erkännande och omfördelning

This study was about disability organisations opinion concerning ICF: s importance in their work to receive the same recognition and human rights for their members as citizens. The aim has been to elucidate disability organisations awareness about and use/non use of ICF and to increase the understanding of ICF: s importance for recognition and redistribution. Three different methods have been used: literature study, questionnaire survey, both on counties' (27) - and national (26) level and interviews (5) on national level. There is also a distinct difference between the disability organisations that represents people with visible impairments, who don?t think that ICF is so useful and they that represent people with invisible impairments, who thinks that ICF is a useful tool.

Taluppfattningstest med enstaviga ord i brus: Normalvärden för barn i åldrarna 7, 10 och 13 år

Background: Phonemically balanced word lists are used when obtaining speech recognition scores in noise. These lists are designed for adults, but are still used for children. To properly obtain speech recognition scores in noise for children, normative data is needed to show what differences there are to be expected between children of different ages. Purpose: The main purpose is to obtain normative data for children in the ages of 7, 10 and 13 years for speech recognition scores in noise using words and to compare these with each other and with normative data of adults. A further purpose is to examine if there is any practice- or exhaustion effect to be seen when obtaining speech recognition scores in noise for children in the ages of 7, 10 and 13 years.Material: The participants were ten 7-year-olds, ten 10-year-olds and ten 13-year-olds.

Nollavräkning av entreprenadprojekt: Teoretisk grund och praktisk betydelse

The purpose of this study is to investigate the method called zero recognition that is used in accounting for construction contracts when the outcome is uncertain. When this is the case it is hard to make the necessary estimates needed for the percentage of completion method to be used. Both the meaning of the method from an accounting perspective and the practical importance and purpose of the method is investigated. The method used for this study is the qualitative one and the deductive model is used to relate the theory with the empirical research. The theoretical background consists of accounting theory and theories about individuals, companies and markets.

Provrumsbelysning

The fitting room is an important part of a clothing store, it's often where the customer decides if they want to buy the garment or not. Therefore it is important that the customer can feel safe and comfortable when they are trying the clothing. A typical fitting room in Sweden today has only one bright spotlight that emits light either towards the face or from the ceiling above. This study explores possible lighting solutions that take into account the customer's experience in the fitting room.The study aim to increase understanding of the importance of a good light in fitting rooms, so that customers gets a nice experience and that clothes, body shape and facial features are shown in a natural way. The issue therefore included how lighting can affect the customer's perception of the clothing and how the perception of body shape, facial features and the clothes change in different lighting solutions.To answer these questions, observations were made in various clothing stores, followed by an experimental study divided into two parts.
