A new optical concept for compact digital image acquisition devices with large field of view is developed and proofed experimentally. Archetypes for the imaging system are compound eyes of small insects and the Gabor-Superlens. A paraxial 3×3 matrix formal ...
This chapter describes tools and techniques that facilitate a gentle introduction to fascinating concepts in digital image processing from four leading universities. Equipped with informative visualizations and a user-friendly interfaces, these modules are ...
A serious effort has been made in developing accurate and efficient bidirectional goniophotometric devices for detailed studies of Complex Fenestration Systems, capable of measuring BTDFs and/or BRDFs in an appropriate way. The existing instruments are alm ...
We present a virtual digital camera sensor, whose aim is to simulate a real (physical) image capturing sensor.To accomplish this task, the virtual sensor operates in two steps. First, it accepts a physical description of agiven scene and simulates the enti ...
Visual information, in the form of images and video, comes from the interaction of light with objects. Illumination is a fundamental element of visual information. Detecting and interpreting illumination effects is part of our everyday life visual experien ...
Efficient collection and redistribution of the direct and diffuse components of daylight in buildings remains a major objective of advanced fenestration systems. Such systems, including novel solar blinds, new glazing or coating materials and daylight-redi ...
Digitally, panoramic pictures can be assembled from several individual, overlapping photographs. While the geometric alignment of these photographs has retained a lot of attention from the computer vision community, the mapping of colour, i.e. the correcti ...
The development of plastic card printers has led to the widespread use of identity documents printed on plastic cards, such as ID cards, driving licenses and access key cards. This paper presents a new security feature based on a technique for embedding a ...
Many daylighting applications require a precise knowledge of the directional transmission features of advanced fenestration materials. These photometric properties are described by a bi-directional transmission distribution function (BTDF), whose experimen ...
A novel approach to shadow detection is presented in this paper. The method is based on the use of invariant color models to identify and to classify shadows in digital images. The procedure is divided into two levels: first, shadow candidate regions are e ...
