Abstract:

Autonomous cars are now becoming a reality, but there are still technical hurdles needed to be overcome for the technology to be safe and reliable. One of these issues is the cars’ ability to estimate braking distances. This function relies heavily on one parameter, friction. Friction is difficult to estimate for a car since the friction coefficient is dependent on both surfaces in contact - the tires and the road. This thesis presents anovel approach to the problem using a neural network classifier trained on features extracted from images of the road. One major advantage the presented method

Self-adaptive systems have limited time to adjust their configurations whenever their adaptation goals, i.e., quality requirements, are violated due to some runtime uncertainties. Within the available time, they need to analyze their adaptation space, i.e., a set of configurations, to find the best adaptation option, i.e., configuration, that can achieve their adaptation goals. Existing formal analysis approaches find the best adaptation option by analyzing the entire adaptation space. However, exhaustive analysis requires time and resources and is therefore only efficient when the adaptation

Abstract:

Cette thèse propose une nouvelle approche de la vision par ordinateur, insistant sur le rôle joué par les différentes informations et connaissances présentes dans un système intégré de vision. Ces connaissances peuvent être vues comme un but à atteindre dans la chaine de traitement ou comme un instrument pour guider ces différents traitement. Ce double rôle est mis en évidence en insistant sur la gestion des informations disponibles à tout moment pour effectuer la tâche de reconnaissance. Une approche distribuée est proposée, sous la forme d'un système multi-agents, où chaque agent est spécial

Abstract:

Under de senaste året har modeller för djupinlärning använts inom nästa alla områden, från industri till akademi, särskilt för bildklassifikation. Dessa modeller är dock enorma i storlek, med miljontals parametrar, vilket gör det svårt att distribuera till mindre enheter med begränsade resurser såsom mobiltelefoner. Denna studie tar upp små modeller av faltningsnätverk som är toppmoderna inom djupinlärning och vars storlek är lämplig för mobilapplikation. Syftet med denna studie är att utvärdera prestanda på faltningsnätverken Xception, InceptionV3 och MobilNetV2 för att underlätta vid valbesl

Abstract:

Artificial Handwriting Recognition (AHR) systems are currently developed in a largely ad hoc fashion. The central premise of this work is the need to return to first principles and identify an underlying rationale for the representations used in handwriting recognition. An interdisciplinary approach is advocated that combines the perspectives of cognitive science and pattern recognition engineering. Existing surveys of handwriting recognition are reviewed and an information-space analogy is presented to model how features encode evidence. Handwriting recognition is treated as an example of a s

Abstract:

Maps are important for both human and robot navigation. Given a route, drivingassistance systems consult maps to guide human drivers to their destinations. Similarly, topological maps of a road network provide a robotic vehicle with information about where it can drive and what driving behaviors it should use. By providing the necessary information about the driving environment, maps simplify both manual and autonomous driving. The majority of existing cartographic databases are built, using manual surveys and operator interactions, to primarily assist human navigation. Hence, the resolution o

Självkörande fordon kan minska trafikstockningar och minska antalet trafikrelaterade olyckor. Då det i framtiden kommer att finnas miljontals autonoma fordon krävs en bättre förståelse av omgivningen. Syftet med detta projekt är att skapa ett externt automatiskt trafikledningssystem som kan upptäcka och spåra 3D-objekt i en komplex trafiksituation för att senare skicka beteendet från dessa objekt till ett större projekt som hanterar med att 3D-modellera trafiksituationen. Projektet använder sig av Tensorflow ramverket och YOLOv3 algoritmen. Projektet använder sig även av en kamera för att spel

Abstract:

Colorectal cancer is the second cause of cancer death in the world. Aiming to early detect and prevent this type of cancer, clinicians perform screenings through the colon searching for polyps (colorectal cancer precursor lesions).If found, these lesions are susceptible of being removed in order to further ana-lyze their malignancy degree. Automatic polyp segmentation is of primary impor-tance when it comes to computer-aided medical diagnosis using images obtained in colonoscopy screenings. These results allow for more precise medical diagnosis which can lead to earlier detection.This project

Abstract:

This project contributes to the problem of mobile robot self-navigation within a rectilinear framework based on visual data. It proposes a number of vision systems based on detection of straight lines in images captured by a robot using the Hough transform and artificial neural networks as core algorithms. The Hough transform is a robust method for detection of basic features (Boyce et al 1987). However, it is so computationally demanding that it is not commonly used in real time applications and applications which utilise anything but small images (Song and Lyu 2005).

Abstract:

Mestrado em Engenharia Mecânica<br>Vision systems have already proven to be a useful tool in various elds. The ease of their implementation, allied to their low cost mean that their growth potential is immense. In this dissertation it is proposed a approach to measure strains in metallic surfaces, using stereo vision. This approach is based on the 3D DIC. This method measures the strain of the surface by dividing this surface in small sections, called subsets, and iteratively nding the equation that describes its shape variation through time. However, calculating the transformation of
