Color Management of Printers by Regression over Enclosing Neighborhoods

摘要: A popular color management standard for controlling reproduction is the ICC profile. The core of profile a look-up-table which maps regular grid device-independent colors to printer colorspace. To estimate from sample input-output colors, local linear regression has been shown work better than other methods. An open problem in how define locality or neighborhood each regressions. In this paper, new adaptive definitions and regularized are proposed address problem. enclose test sample, motivated by result showing they yield bounded estimation variance. experiment shows that both regularization neighborhoods can lead significant reduction error.
