Abstract:

A software component is, in a general sense, a piece of software that can be safely reused and flexibly adapted by some other piece of software. The safety can be ensured by a type system that guarantees the right usage of the component; the flexibility stems from the fact that components are parametrizable over different aspects affecting their behaviours. Component-oriented programming (COP), a programming style where software would be built out of several independent components, has for a long time eluded the software industry. Several reasons have been raised over time, but one that is con

Abstract:

Using an exploratory research design approach, this thesis aims to provide in-depth knowledge of adult visitors’ engagement in suburban neighbourhood parks. This research explored adult visitors’ behaviours and activities in park settings with integrated qualitative and quantitative analysis from the objective and subjective data. The findings revealed that adults engaged differently in the park spaces when compared by age groups, and multiple factors affecting park use could create opportunities for the social sustainability of the neighbourhood. The outcomes of this research are a contributi

The present research try to analyze the objectively patterns of visitor behavior focused on 5 and 12 years old kids, which visited the museums of the city of Girona in a non organized tour. We combined different methodologies for the data collection: survey, non participant direct observation and symbolic language from offered and self-administered written response. As a result, we know how children interact with museum materials, how they make relations with the different group members, how they use supplementary materials to do the visit, what itinerary they do, how they visit the rooms, wha

Abstract:

La Pattern Recognition è lo studio di come le macchine osservano l'ambiente, imparano a distinguere i pattern di interesse dal loro background e prendono decisioni valide e ragionevoli sulle categorie di modelli. Oggi l'applicazione degli algoritmi e delle tecniche di Pattern Recognition è trasversale. Con i recenti progressi nella computer vision, abbiamo la capacità di estrarre dati multimediali per ottenere informazioni preziose su ciò che sta accadendo nel mondo. Partendo da questa premessa, questa tesi affronta il tema dello sviluppo di sistemi di Pattern Recognition per applicazioni real

Abstract:

A fundamental problem in machine vision is the classifcation of objects which may have unknown position, orientation, or a combination of these and other transformations. The massive amount of data required to accurately form an appearance-based model of an object under all values of shift and rotation transformations has discouraged the incorporation of the combination of both transformations into a single model representation. This Master's Thesis documents the theory and implementation of a hierarchical classifier, named the Information Theoretic Decision Tree system, which has the demonstr

Abstract:

Texture is an important cue in vision and has been analysed in its own right for the last three decades by researchers in psychophysics as well as computer vision and image processing. The three important early vision roles that texture analysis can play include texture classification, texture description and texture segmentation, all of which are pre-requisites for higher levels of analysis namely image interpretation and understanding. It is well known that colour can aid the human vision system in the analysis of many visual phenomena like shape, motion and texture. This notion coupled with

Abstract:

Structural parameters that determine yarn quality include evenness, hairiness and twist. This thesis applies machine vision techniques to yarn inspection, to determine these parameters in a non-contact manner. Due to the increased costs of such a solution over conventional sensors, the thesis takes a wide look at, and where necessary develops, the potential uses of machine vision for several key aspects of yarn inspection at both low and high speed configurations. Initially, the optimum optical / imaging conditions for yarn imaging are determined by investigating the various factors which degr

Abstract:

One of the goals in computer vision is to interpret scene objects and establish relationships between them. One of tire problems associated with this task is that the image to be interpreted and the objects to be recognised correspond to different levels of information. The image is, on the one hand, represented as a collection of pixels in which three-dimensional information is transformed into two-dimensional one under perspective projection dictated by the camera position as well as photometric parameters such as focal length etc. On the other hand, the object is represented as a collection

The thesis describes progress towards the construction of a seeing machine. Currently, we do not understand enough about the task to build more than the simplest computer vision systems; what is understood, however, is that tremendous processing power will surely be involved. I explore the pipelined architecture for vision computers, and I discuss how it can offer both powerful processing and flexibility. I describe a proposed family of VLSI chips based upon such an architecture, each chip performing a specific image processing task. The specialisation of each chip allows high performance to b

Abstract:

Medical imaging is a generic term used to define the use of medical practices to create images of the human body for clinical purpose. Today it includes a wide range of different techniques and these have greatly enhanced the quantity and quality of information available in the clinical practice. The clinician may now obtain a comprehensive view of internal structures of the human body, such as heart, kidney, lung, gut and so on. Computer assistance plays a relevant role in all these clinical applications. Each imaging technique is indeed associated with some kind of specialized workstation wh

Abstract:

The aim of this thesis is to propose a modular vision system for automatic 2D object recognition, to determine its performance (with respect to accuracy, robustness, and efficiency), and to compare its performance to the performance of the neocognitron. Most of the existing vision systems assume that a preprocessed and clean image is provided, and that the parameters of the used algorithms are chosen by the user, depending on the scene under consideration. On this basis it is desired from the proposed system to be: 1)accurate, 2) robust, 3) efficient, and 4) adaptive. The system works under th

Abstract:

The aim of this study is to provide an automatic method for the interpretation of images of objects that are coated with thermal paint. Thermal paint changes colour permanently according to the temperature to which it is heated and can be employed as a temperature gauge where more cumbersome measurement apparatus may not be suitable. Such a gauge requires a means to convert the manifestation of the measurement to the corresponding numerical values. In our case this involves the grouping of ranges of colour together into temperature bands and the extraction of the temperature contours between t
