What is FRep? [HyperFun.org] The Function Representation (or FRep) defines a geometric object by a single real continuous function of point coordinates as It combines many different models like algebraic surfaces skeleton based “implicit” surfaces set-theoretic solids or CSG (Constructive Solid Geometry) sweeps volumetric objects parametric models procedural models Main features of FRep: Defining the function evaluation procedure traversing the constructive tree structure Leaves of the constructive tree are primitives with known types of defining functions Nodes of the tree contain operations and relations Extensibility of primitives, operations, and relations The main goal of this project is to develop a rich system of geometric operations and relations.
Our approach is based on the R-functions - continuous definitions of set-theoretic operations. FRep can also be used to model point-wise object’s properties such as material, density, color. We apply theoretic results in different areas: A. ExplanationoftheLABColorSpace. CIELAB - Color Models - Technical Guides. CIELAB is the second of two systems adopted by CIE in 1976 as models that better showed uniform color spacing in their values.
CIELAB is an opponent color system based on the earlier (1942) system of Richard Hunter called L, a, b. Color opposition correlates with discoveries in the mid-1960s that somewhere between the optical nerve and the brain, retinal color stimuli are translated into distinctions between light and dark, red and green, and blue and yellow. CIELAB indicates these values with three axes: L*, a*, and b*. (The full nomenclature is 1976 CIE L*a*b* Space.) The central vertical axis represents lightness (signified as L*) whose values run from 0 (black) to 100 (white). The color axes are based on the fact that a color can't be both red and green, or both blue and yellow, because these colors oppose each other. CIELAB has become very important for desktop color.
The Lab Color Mode in Photoshop. What's Covered The Need for Device-Independent Color The Lab Color Model Mode Conversion In Photoshop Working With Photo CD Images Selective Color Correction The Lab color mode allows you to work in a device-independent color space (the goal of device-independent color is to create consistent color regardless of the device used to reproduce it). This document provides a brief overview of device independence and the Lab color mode, and offers suggestions on using the Lab color mode in Adobe Photoshop. The Need for Device-Independent Color Different devices produce colors differently.
Colors can also differ on the same device, depending on the image's color model. The Lab Color Model The Commission Internationale d'Eclairage (CIE), an international organization formed to standardize color measurement, developed a color model in 1931 based on the way the human eye perceives color. Mode ConversionIn Photoshop Photoshop uses color modes to determine the color model used to display and print images. Lab color space. CIELAB color space top view CIELAB color space front view The CIE 1976 (L*, a*, b*) color space (CIELAB), showing only colors that fit within the sRGB gamut (and can therefore be displayed on a typical computer display). Each axis of each square ranges from −128 to 128. The Lab color space describes mathematically all perceivable colors in the three dimensions L for lightness and a and b for the color-opponents green-red and blue-yellow.
The terminology "Lab" originates from the Hunter 1948 color space.[1][2]Nowadays "Lab" is frequently mis-used as abbreviation for CIEL*a*b* 1976 color space color space (also CIELAB); the asterisks/stars distinguish the CIE version from Hunter's original version. The Lab color space exceeds the gamuts of the RGB and CMYK color models (for example, ProPhoto RGB includes about 90% all perceivable colors).
