Kai's Power Tools were sold to Corel in 2000 when MetaCreations was closed. [1] There are various versions of Kai's Power Tools. KPT 3, 5, [2] 6, and X sets are compilations of different filters. The program interface features a reward-based function in which a bonus function is revealed as the user moves towards more complex aspects of the tool.
For a graph G, let χ(G) denote the chromatic number and Δ(G) the maximum degree of G.The list coloring number ch(G) satisfies the following properties.. ch(G) ≥ χ(G).A k-list-colorable graph must in particular have a list coloring when every vertex is assigned the same list of k colors, which corresponds to a usual k-coloring.
A comparison between a typical normalized M cone's spectral sensitivity and the CIE 1931 luminosity function for a standard observer in photopic vision. In the CIE 1931 model, Y is the luminance, Z is quasi-equal to blue (of CIE RGB), and X is a mix of the three CIE RGB curves chosen to be nonnegative (see § Definition of the CIE XYZ color space).

[2] While the intention behind CIELAB was to create a space that was more perceptually uniform than CIEXYZ using only a simple formula, [3] CIELAB is known to lack perceptual uniformity, particularly in the area of blue hues. [4] The lightness value, L* in CIELAB is calculated using the cube root of the relative luminance with an offset near black.
log-log plot of F L vs. L A (L A ranges from 10 −4 to 10 4, F L ranges from 10 −4 to 10). The cube root approximation of F L is 0.1715 L A 1/3 In CIECAM02, the reference illuminant has equal energy L wr = M wr = S wr = 100 ) and the reference white is the perfect reflecting diffuser (i.e., unity reflectance, and Y wr = 100 ) hence:
The subsampling scheme is commonly expressed as a three-part ratio J:a:b (e.g. 4:2:2) or four parts, if alpha channel is present (e.g. 4:2:2:4), that describe the number of luminance and chrominance samples in a conceptual region that is J pixels wide and 2 pixels high. The parts are (in their respective order):
In color science, the white point of an illuminant or of a display is a neutral reference characterized by a chromaticity; all other chromaticities may be defined in relation to this reference using polar coordinates.
