Painting in High Dynamic Range
Journal of Visual Communication and Image Representation, 2007We present a novel approach that allows users to intuitively and interactively manipulate High Dynamic Range (HDR) images using commonly available Low Dynamic Range (LDR) displays. This solves the problem of how to draw with contrasts that are much larger than the monitor can display.

Extension Of The Dynamic Range Of Active Laser Range Finders
SPIE Proceedings, 1989Active range finders based on triangulation have proven to be very useful when dense depth maps are required. A number of range finders utilize linear or bidimensional arrays of photodetectors (photodiodes or MOS-type) to provide depth information. A practical limitation of these sensors is their relatively low saturation level.

Phantoms and Dynamic Range in Mammography
Radiation Protection Dosimetry, 1993The phantoms used to evaluate the imaging properties of a mammography system include details and/or test objects embedded in a bulk with a constant X ray transmission all over the image plane. On the other hand, the X ray beam transmitted by the breast presents a wide variation of intensity in the image plane.

On dynamic behavior of full range CNNs
Proceedings of the 2003 International Symposium on Circuits and Systems, 2003. ISCAS '03., 2003Cellular neural networks are described by large sets of coupled nonlinear differential equations. Two CNN models were proposed in the literature: the original Chua-Yang model and the Full-Range model, that were exploited for VLSI implementations. We show that, even if the two models exhibit similar properties, they are not topologically equivalent, i.e.

Dynamic range and visual perception
Proceedings of the 4th symposium on Applied perception in graphics and visualization, 2007Broadly speaking, the human visual system attempts to discount illumination so it can extract surface shapes and reflectance characteristics, independent of one's surroundings. This elucidates the purpose of vision, to quickly identify and categorize objects so the higher brain can seek opportunities and avoid obstacles and dangers that may be present.

Dynamic range of the Barber filters
Signal Processing, 2006In this paper, the filters which consist of two parallel transmission paths (channels) will be presented. Each of them contains two multipliers and a lowpass filter, composed of standard components.The influence of non-identical channels will be considered towards the output signal.
