Cluster Dot Dithering is one of the most common halftoning techniques. It is fast, low in complexity and allows for variability and inconsistencies in point spreads in printer outputs. Determination of the basic dither cell size is critical for the quality of the halftoning. There is a basic tradeo between large and small cell sizes: spatial resolution vs gray tone resolution. Large dither cell...

This work uses the S-CIELAB color model to compare images that have been calibrated and processed using a colorimetric dithering method which simulates increments in viewing distance. Firstly, we obtain XYZ calibrated images by applying the appropriate color transformations to the original images. These transformations depend on whether the image is viewed on a display device or encoded by a ca...

This paper presents a BIST scheme to test and calibrate on-chip DAC and ADC and to improve both linearity and resolution of converters using a built-in sigma-delta modulator. We use a dithering dynamic element matching (DEM) techniques. A first-order sigma-delta modulator is used to sample DAC outputs because of high linearity of its outputs with high oversampling rate (OSR). The scheme is capa...

A new method of direct and continuous measurement of the spring constant of single molecule or molecular complex is elaborated. To that end the standard force spectroscopy technique with functionalized tips and samples is combined with a small dithering of the tip. The change of the dithering amplitude as a function of the pulling force is measured to extract the spring constant of the complex....

numerous advantages in quality color rendering. We address lent comprehensive reviews have been published, including some theoretical issues, design and optimality issues, printer Ulichney [1], Roetling and Loce [2], Jones [3], and Kang compensation issues, and color quality issues that pertain to [4]. A brief orientation is given here. Ordered dither is the the development and use of stochasti...

This paper discusses possible extensions of error-diffusion dithering algorithms for color devices that give a more accurate reproduction of colors than previous algorithms. The main difference of the method presented here and others is that usually color channels are regarded separately, whereas we look at them together as one color value that is used to select the closest output color. This a...

Similar expressions hold for b n. To achieve the modulation, the array is weighted with the time-varying linear combination c n = (t)a n + f1 ? (t)gb n (5) where (t) is a smoothly varying function having an amplitude ranging from zero to one and a period much less than the reverberation time of the acoustic enclosure. This time-varying linear combination results in a time-varying beamwidth of r...
