Abstract
The Mottle analysis method is widely used to describe ISO 13660 and improved by ISO 24790. However, this method showed not enough satisfied correlation for ours. In this paper, we propose a new method for measuring effective noise analysis in solid area. We will name it as 'Solid-Mottle'. It is phenomenon of printing optical-density non-uniformity at solid-black, and it is occurred on laser-printers. The purpose of present paper is to offer an analysis of Solid-Mottle defect, test pattern and method for measuring. Quantified Solid-Mottle is measured based on psychophysical experiment. Parameter A and JNDmottle is determined by human experiment. By conducting five-fold cross-validation, the strong correlation was obtained between the proposed method and perceived scales: the correlation coefficient r is 0.94, RMSE (Root Mean Square Error) is 0.34, respectively. In addition, the F1-measure score is 0.92 by SVM (Support Vector Machine) approach.
