Billedbehandling

De seneste år er digital farvelægning af gamle fotografier blevet en populær måde at bringe fortiden til live. Det er blevet muligt at farvelægge gamle billeder i så god en kvalitet, at det næsten er blevet svært at kende forskel på et nyt farvefoto og så et farvelagt sort-hvid fotografi. Billederne får et helt nyt liv – og mange af dem ser ud som om de næsten er taget i går.Forfatteren Arne Kjær Hansen er en af dem, der har brugt teknikken. Han har fundet 55 billeder frem fra det gamle Aarhus og farvelagt dem efter de farver, der blev brugt, da billedet blev taget. Der findes billeder fra sidst i 1800-tallet til 1930’erne.Datidens gader og de mennesker, der befolkede dem, kommer pludselig tæt på, når man sidder og betragter Arne Kjær Hansens værker. Hvert enkelt foto er forklaret med en tekst forfattet af historiker Jørgen Mührmann Lund.

Bogen henvender sig til både begyndere og øvede Photoshop-brugere og kommer vidt omkring i beskrivelsen af fremgangsmåder og begreber, som alle tager afsæt i de emner, der er relevante i forhold til moderne billedbehandling. Bogen søger at gå i dybden med en lang række af de teknikker og fremgangsmåder, som må anses for relevante for den digitale fotograf og andre, som ønsker at arbejde med billedbehandling. Den består af både forklaringer og teori, men også en masse håndgribelige og pædagogiske fremgangsmåder.Kapitlerne er opdelt efter overordnet emne og alle fremgangsmåder og beskrivelser er gjort så velillustrerede som muligt både i form af skærmbilleder og eksempelbilleder.Bogen dækker både den danske og engelske version af Photoshop og behandler emner, som kan udføres i både Photoshop CS4 og Photoshop CS4 Extended.Blandt de mange emner og discipliner, som bogen ser nærmere på, er:+ Det digitale billedes opbygning+ Farvestyring+ Photoshop-vinduet+ Adobe Bridge+ Beskæring, opretning, rotering+ Opløsning og billedstørrelse+ Fritlægning og markering+ Justering af farver og kontrast+ Retouchering+ Afhjælpning af røde øjne+ Sort/hvid-konvertering+ Transformationer+ Afhjælpning af støj+ Skarphedsteknikker+ Smart Objects+ Arbejde med RAW+ HDR-billeder+ Forsvindingspunkt+ Zoomify+ Smart Filters+ Panoramabilleder+ Udskrivning+ Billeder til web+ Og meget andet...

Lightroom er det mest populære program blandt professionelle fotografer til efterbehandling og organisering af digitale fotos. Programmets brugervenlighed betyder dog, at også mange amatørfotografer har taget Lightroom til sig.I dette hæfte kan du lære, hvordan du på optimal og effektiv vis arbejder med dine billeder i programmet. Hæftet er logisk bygget op som et opslagsværk, så du hurtigt kan danne dig overblik over de enkelte funktioner.Du vil finde ud af, hvordan du bedst muligt kan bruge biblioteksdelen af programmet til at organisere og sortere dine billeder ved hjælp af de forskellige katalogiseringsværktøjer.Desuden skal vi kigge på de mange efterbehandlingsfunktioner, der lader dig gøre alt fra at rette lys- og farveforhold til at foretage reelle billedmanipulationer med retoucheringsværktøjet.Hæftet er skrevet til Lightroom 5, men kan i vid udstrækning også bruges til ældre versioner af programmet.

In the big data era, increasing information can be extracted from the same source object or scene. For instance, a person can be verified based on their fingerprint, palm print, or iris information, and a given image can be represented by various types of features, including its texture, color, shape, etc. These multiple types of data extracted from a single object are called multi-view, multi-modal or multi-feature data. Many works have demonstrated that the utilization of all available information at multiple abstraction levels (measurements, features, decisions) helps to obtain more complex, reliable and accurate information and to maximize performance in a range of applications.This book provides an overview of information fusion technologies, state-of-the-art techniques and their applications. It covers a variety of essential information fusion methods based on different techniques, including sparse/collaborative representation, kernel strategy, Bayesian models, metric learning, weight/classifier methods, and deep learning. The typical applications of these proposed fusion approaches are also presented, including image classification, domain adaptation, disease detection, image restoration, etc. This book will benefit all researchers, professionals and graduate students in the fields of computer vision, pattern recognition, biometrics applications, etc. Furthermore, it offers a valuable resource for interdisciplinary research.

This book provides a comprehensive guide to 3D Light-Field camera based imaging, exploring the working principles, developments and its applications in fluid mechanics and aerodynamics measurements. It begins by discussing the fundamentals of Light-Field imaging and theoretical resolution analysis, before touching upon the detailed optics design and micro-lens array assembly. Subsequently, Light-Field calibration methods that compensate for optical distortions and establish the relations between the image and real-word 3D coordinates are covered. This is followed by Light-Field 3D reconstruction algorithms which are elaborated for micrometer-scale particles and centimeter-scale physical models. Last but not least, implementations of the preceding procedures to selected fundamental and applied flow measurement scenarios are provided at the end of the book.  Development and Application of Light-Field Cameras in Fluid Measurements gives an in-depth analysis of each topic discussed, making it ideal as both an introductory and reference guide for researchers and postgraduates interested in 3D flow measurements.

The age of Advanced Air Mobility (AAM) is upon us, and in ushering new ways to connect and travel, this wave of technology has been compared to GPS and cloud computing. However, new technologies like AAM require tools to build, expand, and understand the capabilities. This book describes an effective and efficient, complete solution to the large-scale, unmanned aircraft systems (UAS) traffic management problem. The authors present a detailed perspective and solutions to some of the major problems involved in coordinating thousands of autonomous vehicles including: virtual highway (lane) creation, strategic deconfliction of flights, dynamic deconfliction, UAS agent behavior learning, anomalous trajectory detection and classification, as well as a set of simulation results for a variety of scenarios (city package delivery, earthquake supply delivery, coalition force coordination through the lane reservation system, etc.).
