Real environments are much more complex than indoor environments and require advanced tools to deal, for instance, with sharp brightness variations.
In traditional multiresolution fusion algorithms, such as [9, 31, 32], the multiresolution coefficients with larger absolute value are considered as sharp brightness changes or salient features in the corresponding source image, such as the edges, contours, and region boundaries, and so on.
The high contrast screen produces sharp, bright images that can be viewed easily from any angle, and the monitor's high brightness means that it can be easily viewed even when the surrounding light is bright.
Consumers who wish to hold the E-PL1 up to their eye rather than use the LCD will appreciate that the optional VF-2, which provides 1.15x magnification and a 100percentt field of view with sharp resolution, brightness and contrast.
It features a screen size of 3.4 inches, 480 x 854 resolution, a contrast ratio of 1,000 1, and 500 cd/m2 brightness (Sharp claims the image quality is the best in the industry).
Several nanomaterials have shown great promise in imaging due to their intrinsic imaging characteristics, such as their brightness, sharp bandwidth and long-term stability (e.g., fluorescent agents, such as QDs [72], magnetic NPs in MRI [73] and colloidal AuNPs [74]).
The world's lightest2 interchangeable single focal length lens LUMIX G 14 mm / F2.5 ASPH features a 14mm (35 mm camera equivalent: 28 mm) wide angle and F2.5 brightness with sharp, high contrast image rendering.
Sharp changes in image brightness are very important in boundary detection.
They don't look especially sharp, big or bright — in fact, the K5 offers no screen-brightness control at all — and there's no crossfading or gentle panning effects; you can't even specify the timing of the slides.
It is always the case, too, that there is a sharp peak in the lunar brightness when full, thought to be due to the way light reflects from its pitted airless surface.
A lens must cover the area of a camera's film format to yield an image adequately sharp and with reasonably even brightness from the centre to the corners of the film.
