Reflective Practice: How the World Bank Explored Its Own Biases?
While many international organisations have independent evaluations, including the International Monetary Fund (IMF) and World Health organization (WHO), uniquely the World Bank in its 2015 World Development Report sought to ascertain the potential biases that influence how its staff interpret evidence and influence policy. Here, we describe the World Bank’s study design, including experiments ...
متن کاملColor transformation for the compression of CMYK images
A CMYK image is often viewed as a large amount of device-dependent data ready to be printed. In several circunstances, CMYK data needs to be compressed, but the conversion to and from device-independent spaces is imprecise at best. In this paper, with the goal of compressing CMYK images, color space transformations were studied. In order to have a practical importance we developed a a new trans...
متن کاملبررسی امکان رسیدن به طیفهای رنگی مختلف با ترکیب رنگدانههای نانو و میکرونی در سیستم CMYK
در تحقیق حاضر نانو رنگدانههای سرامیکی CoAl2O4 (فیروزهای)، Au (سرخابی)، (Ti,Cr,Sb)O2 (زرد) و CoFe2O4 (سیاه) که برای تزئین کاشیهای سرامیکی توسط جت پرینتر استفاده میشوند، توسط نرمافزار Colours با یکدیگر ترکیب شدند. هدف از این امر بررسی امکان رسیدن به طیفهای رنگی مختلف توسط چهار رنگ سیستم CMYK بود. برای مقایسه رنگدانههای نظیر میکرونی CoAl2O4، Cd(S,Se):ZrSiO4، (Ti,Cr,Sb)O2 و CoFe2O4 نیز مورد ...
متن کاملThe JCB will let your data shine in RGB
CMYK vs. RGB Color images are printed on paper by separating their colors into four component parts: cyan, magenta, yellow, and black ( CMYK ). Each of the colors in an image is created by assigning a percentage from 0–100 to each of the aforementioned colors (for example, a red color could be created from 0% cyan, 100% yellow, 100% magenta, and 0% black). The color image is then printed on a m...
متن کاملOn independent color space transformations for the compression of CMYK images
Device and image-independent color space transformations for the compression of CMYK images were studied. A new transformation (to a YYCC color space) was developed and compared to known ones. Several tests were conducted leading to interesting conclusions. Among them, color transformations are not always advantageous over independent compression of CMYK color planes. Another interesting conclu...
