Printing quality assessment by image processing and color prediction models / Évaluation de la qualité d'impression par traitement d'images et modèles de prédiction couleur

Nébouy, David 16 December 2015 (has links)
L'impression, bien qu'étant une technique ancienne pour la coloration de surfaces, a connu un progrès considérable ces dernières années essentiellement grâce à la révolution du numérique. Les professionnels souhaitant remplir les exigences en termes de qualité du rendu visuel de leurs clients veulent donc savoir dans quelle mesure des observateurs humains sont sensibles à la dégradation d'une image. De telles questions concernant la qualité perçue d'une image reproduite peuvent être séparées en deux sujets différents: La qualité de l'impression, comme la capacité d'un système d'impression à reproduire fidèlement l'image d'origine, et la qualité d'une image imprimée, résultant à la fois de la qualité de reproduction, mais aussi de la qualité même de l'image numérique d'origine. Ce premier concept repose sur une analyse physique de la façon dont l'image d'origine est dégradée lors de son transfert sur un support, et nous proposons de la coupler avec une analyse sensorielle, visant à évaluer des attributs perceptuels et leur donner une valeur sur une certaine échelle, déterminée par des échantillons de référence classés par un ensemble d'observateurs. Le second concept inclut cette dégradation due à l’impression mais aussi la qualité perçu de l’image d’origine, qui ne fait pas parti de notre étude. Notre approche consiste d'abord à définir les différents indices de qualité, basés sur des critères mesurables en utilisant des outils d'évaluation basés sur des algorithmes "objectifs" de traitement d'image et des modèles optiques, sur une image imprimée-scannée. Thèse réalisée au Laboratoire Hubert Curien / Printing, though an old technique for surface coloration, considerably progressed these last decades especially thanks to the digital revolution. Professionals who want to meet the demands in terms of quality regarding the visual rendering of their clients thus want to know to which extent human observers are sensitive to the degradation of an image. Such questions regarding the perceived quality of a reproduced image can be split into two different topics: the printing quality as capacity of a printing system of accurately reproduce an original digital image, and the printed image quality which results from both the reproduction quality and the quality of the original image itself. The first concept relies on physical analysis of the way the original image is deteriorated when transferred onto the support, and we propose to couple it with a sensorial analysis, which aims at assessing perceptual attributes by giving them a value on a certain scale, determined with respect to reference samples classified by a set of observers. The second concept includes the degradation due to the printing plus the perceived quality of the original image, not in the scope of this work. In this report, we focus on the printing quality concept. Our approach first consists in the definition of several printing quality indices, based on measurable criteria using assessment tools based on “objective” image processing algorithms and optical models on a printed-then-scanned image.

Minimumkrav för ett CI-system

Kiendys, Petrus, Al-Zara, Shadi January 2015 (has links)
När en grupp utvecklare jobbar med samma kodbas kan konflikter uppstå med avseende på implementationen av moduler eller delsystem som varje utvecklare individuellt jobbar på. Dessa konflikter måste snabbt lösas för att projektet ska fortskrida och inte stagnera. Utvecklare som sällan kommunicerar framför ofta okompatibla moduler eller delsystem som kan vara svåra eller omöjliga att integrera i kodbasen, detta leder ofta till s.k. “integration hell” där det kan ta väldigt lång tid att anpassa ny kod till en befintlig kodbas.En strategi som man kan ta till är “continuous integration”, ett arbetssätt som erbjuder en rad fördelar när man jobbar i grupp på en gemensam kodbas. Continuous integration är möjligt att tillämpa utan verktyg eftersom detta är ett arbetssätt. Däremot kan processen stödjas av ett s.k. “CI-system” som är något av en teknisk implementation eller påtagligt införlivande och stöd för arbetsmetoden “continuous integration”.Denna rapport syftar till att ge en inblick i vad ett CI-system är och vad den principiellt består av. Vi undersöker vad ett CI-system absolut måste bestå av genom en litteraturundersökning och en marknadsundersökning. Vi ställer upp dessa beståndsdelar som “funktionella” och “icke-funktionella” krav för ett typiskt CI-system. Vi kan på så vis kvantifiera och kategorisera olika komponenter och funktionaliteter som bör innefattas i ett typiskt CI-system. I denna rapport finns även ett bihang som visar hur man kommer igång med att bygga en egen CI-server mha. CI-systemmjukvaran “TeamCity”.Slutsatsen av vår rapport är att CI-system är ett viktigt redskap som kan underlätta mjukvaruutveckling. Med hjälp av CI-system kan man stödja utvecklingsprocessen genom att bl.a. förhindra integrationsproblem, automatisera vissa delar av arbetsprocessen (kompilering av källkod, testning av mjukvara, notifikation om stabilitet av kodbas och distribution av färdig mjukvara) samt snabbt hitta och lösa integrationsfel. / When a group of developers work on the same code base, conflicts may arise regarding the implementation of modules or subsystems that developers individually work on. These conflicts have to be resolved quickly in order for the project to advance at a steady pace. Developers who do not communicate changes or other necessary deviations may find themselves in a situation where new or modified modules or subsystems are impossible or very difficult to integrate into the mainline code-base. This often leads to so called “integration hell” where it could take huge amounts of time to adapt new code into the current state of the code-base. One strategy, which can be deployed to counteract this trend is called “continuous integration”. This practice offers a wide range of advantages when a group of developers collaborates on writing clean and stable code. Continuous integration can be put into practice without the use of any tools as it is a “way to do things” rather than an actual tool. With that said, it is possible to support the practice with a tangible tool called a CI-system.This study aims to give insight into the makings of a CI-system and what it fundamentally consists of and has to be able to do. A study of contemporary research reports regarding the subject and a survey was performed in order to substantiate claims and conclusions. Core characteristics of CI-systems are grouped into “functional requirements” and “non-functional requirements (quality attributes)”. By doing this, it is possible to quantify and categorize various core components and functionalities of a typical CI-system. This study also contains an attachment which provides instructions of how to get started with implementing your own CI-server using the CI-system software ”TeamCity”. The conclusion of this study is that a CI-system is an important tool that enables a more efficient software development process. By making use of CI-systems developers can refine the development process by preventing integration problems, automating some parts of the work process (build, test, feedback, deployment) and quickly finding and solving integration issues.
