Useful Color Calculators and Spreadsheets - 8 views
-
*CIE Color Calculator: Converts among most of the CIE color models as well as providing correlated color temperature and standard RGB conversions. *Companding Calculator: Converts among luminance, CIE L*, density and gamma. Includes both a numeric calculator and a graphical display. *Color Difference Calculator: Computes color differences using several different methods (CIE1976, CIE1994, CIE2000, CMC). *Chromatic Adaptation Calculator: Converts colors between reference whites using different chromatic adaptation algorithms. *CIE Spectral Display: Calculates and displays many useful CIE functions, such as the Standard Observers, the Standard Illuminants and blackbody radiators. *Spectral Calculator Spreadsheets: Calculates colorimetry, densitometry and RGB values from your spectral data. *Levels Calculator: See how you lose levels when you pass data through curves. *ColorChecker Calculator: Performs many spectral calculations on the 24 colors of the ColorChecker chart. *ColorChecker RGB Summaries, Spreadsheets and Lab TIFF File: You will find three things on this page, a) summaries of the ColorChecker colors, expressed in each of many standard RGB color spaces, b) spreadsheets that allow you to find which RGB color space is closest to your RGB values, and c) a computer generated Lab TIFF file of the ColorChecker. *Munsell Display Calculator: Displays the Munsell color set (2734 colors) in xyY, Lab and Luv. This is a useful tool for evaluating uniform perceptual color spaces. Also included is an explanation of the infamous "blue turns purple" problem often seen with printer profiles. *Dot Gain Calculator: Performs the standard Murray-Davies dot gain equation to your density measurements. *Dot Gain from Lab or Profile: Two spreadsheets which calculate dot gain from Lab measurements, also allowing you to measure the dot gain of a CMYK ICC printer profile.

Color calculatorConverts color data to different color standards (RGB, CMYK, L*ab, L*ch, L*uv, Hunter, XYZ etc.). All the math implemented in this calculators is available in the math/formulas page.
-
Monitor color calibration, Monitor color resolution, Create color harmonies, Color delta/comparison math, Color tutorials formulas to calculate color differences. All of them refers to the CIE-L*ab color space.Each formula is written as a "neutral programming function", easy to be translate in any specific computer language.We did not post obvious deltas which involve a simple subtraction of two values.

Let's say we succeed in creating a system that knows a lot, and can figure a lot out. How can we interact with it? It's going to be a website: www.wolframalpha.com. With one simple input field that gives access to a huge system, with trillions of pieces of curated data and millions of lines of algorithms.

Pillbox - prototype pill identification system - 3 views

The National Library of Medicine is partnering with the Food and Drug Administration to enhance patient safety by providing an identification and reference system for solid-dosage medications.Pillbox's data and search engine is also accessible through an API.
-
enables to search unknown solid-dosage medications (tablets/capsules) based on physical characteristics and images. The system combines high-resolution images of tablets and capsules with FDA-approved appearance information (imprint, shape, color, etc.) to enable users to visually search for and identify an unknown solid dosage pharmaceutical. This system is designed for use by emergency physicians, first responders, other health care providers, Poison Control Center staff, and concerned citizens.

Usage: Hover the cursor over any cell in the matrix. A small box gives details on mashups for that API combination. Top links in hover box bring you to that API's reference page. Links in body of hover box take you directly to the mashup. Not all combinations have mashups & only those with the 'º' indicator currently have entries. Cells at the intersection of same API (ex: Amazon+Amazon) list any other examples for that API.
Note that there are two views into the matrix: the default view shows only those APIs for which mashups have been added to the database. The second view shows all APIs regardless of whether there's currently a mashup registered. It's big. Definitions: What is a mashup anyway? As always, it's good to check Wikipedia's definition, but essentially a "mashup" is a web-based application built through (creative) combination of data from multiple sources. Often, but by no means always, this data is retrieved by using a vendor's API such as those listed here. (An API? Also at Wikipedia.) Some recent press may also help explain: BusinessWeek's "Mix, Match and Mutate", The Economist's "Mashing the Web". Background: This is an experiment. It is intended to be both a reference point and also a visualization. What you see here today will change both in content and form shortly. I am quite interested in seeing the 'space' in which mashups exist. Clearly, some APIs such as Google Maps, appear to be more widely used than others. UI Issues: Cross-browser support is good but not complete. Sometimes it can b
