Image Dithering Based on the Wavelet Transform
In this paper, a method for compensating the softening effect of the error diffusion algorithms, and a new dithering technique that emphasizes the details of images and is based entirely on the wavelet transform, are presented.
متن کاملA deadline on malaria.
key international organizations and businesses—set a timetable for comprehensive malaria control in Africa by the end of 2010. Secretary-General Ban has thrown down the gauntlet: there is no reason why a million or more children should die every year of a largely preventable and wholly treatable disease. The operational objective is to ensure that crucial interventions are taken continent-wide ...
متن کاملsurvey on the rule of the due & hindering relying on the sheikh ansaris ideas
قاعده مقتضی و مانع در متون فقهی کم و بیش مستند احکام قرار گرفته و مورد مناقشه فقهاء و اصولیین می باشد و مشهور معتقند مقتضی و مانع، قاعده نیست بلکه یکی از مسائل ذیل استصحاب است لذا نگارنده بر آن شد تا پیرامون این قاعده پژوهش جامعی انجام دهد. به عقیده ما مقتضی دارای حیثیت مستقلی است و هر گاه می گوییم مقتضی احراز شد یعنی با ماهیت مستقل خودش محرز گشته و قطعا اقتضاء خود را خواهد داشت مانند نکاح که ...
15 صفحه اولForced Random Dithering: Improved Threshold Matrices for Ordered Dithering
This paper examines the possibilities of improving halftoning techniques using dispersed dots. This corresponds to finding micro-dot distributions that approximate the intensity levels that have to be rendered. A widely used halftoning method is ordered dithering, which uses a threshold matrix to decide if a micro-dot should be set in the output image. A way to generate improved threshold matri...
متن کاملAdaptive cluster dot dithering
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...
