Evolution of the Luminosity Function and Colors of Galaxies in a Λ Cold Dark Matter Universe
The luminosity function of galaxies is derived from a cosmological hydrodynamic simulation of a Λ cold dark matter (CDM) universe with the aid of a stellar population synthesis model. At z = 0, the resulting B-band luminosity function has a flat faint end slope of α = −1.15 with the characteristic luminosity and the normalization in a fair agreement with observations, while the dark matter halo...

15 صفحه اولMapping colors from paintings to tapestries: rejuvenating the faded colors in tapestries based on colors in reference paintings
We addressed the problem of recovering or “rejuvenating” colors in a faded tapestry (the target image) by automatically mapping colors from digital images of the reference painting or cartoon (the source image). We divided the overall computational challenge into several subproblems, and implemented their solutions in Matlab: 1) quantizing the colors in both the tapestry and the referent painti...
متن کاملThe Poetry of Colors
Bruce Thacker never took an art class. He never even took a computer class. His degree is in geology, and he fi rst bought a computer in 1990 to track stock investments. Somewhere in the convoluted melange of his linear history, he owned a contemporary art gallery, invested in stocks and real estate, owned a custom photo lab, and was a professional photographer. “Other things that I’ve never ha...
متن کاملUsing Pseudo-Inverse to Eliminate the Limitation of the Number of Colors in Colorimetric Match
An algorithm is suggested for implementation of unlimited primaries in two-constants Kubelka-Munk color matching attempt. Allen's method for tristimulus color matching which was limited to four colorants in two constant theory, dealt with inversable matrices. By application of the pseudo-inverse, it is not necessary to limit the number of primary colors to four as Allen suggested. The suggested...
