Compensating Printer Modulation Transfer Function in Spatial and Color Adaptive Rendering Workflows

2008
Conference Papers

Abstract

Experiments have shown that the quality of printed images depends on the capacity of the printing system to accurately re- produce details. We propose to improve the quality by compensat- ing for the Modulation Transfer Function (MTF) of the printing system. The MTF of the printing system is measured using a mod- ified version of the method proposed by Jang and Allebach [1]. Then the MTF is adaptively compensated in the Fourier domain, depending on the frequency and on the local mean value. This compensation is included within our mathematical framework for Spatial and Color Adaptive Gamut Mapping Algorithms. Results of a category judgment experiment show significant improvement as the printed MTF compensated images obtain the best scores.

Frequency domain

In mathematics, physics, electronics, control systems engineering, and statistics, the frequency domain refers to the analysis of mathematical functions or signals with respect to frequency, rather than time. Put simply, a time-domain graph shows how a signal changes over time, whereas a frequency-domain graph shows how the signal is distributed within different frequency bands over a range of frequencies. A frequency-domain representation consists of both the magnitude and the phase of a set of sinusoids (or other basis waveforms) at the frequency components of the signal.

Fourier transform

In physics and mathematics, the Fourier transform (FT) is a transform that converts a function into a form that describes the frequencies present in the original function. The output of the transform is a complex-valued function of frequency. The term Fourier transform refers to both this complex-valued function and the mathematical operation. When a distinction needs to be made the Fourier transform is sometimes called the frequency domain representation of the original function.

Fourier analysis

In mathematics, Fourier analysis (ˈfʊrieɪ,_-iər) is the study of the way general functions may be represented or approximated by sums of simpler trigonometric functions. Fourier analysis grew from the study of Fourier series, and is named after Joseph Fourier, who showed that representing a function as a sum of trigonometric functions greatly simplifies the study of heat transfer. The subject of Fourier analysis encompasses a vast spectrum of mathematics.
