An Textile Color Degradation Algorithm Based on Spatial Gray Domain

According to the jacquard technology, we contrast the gray bitmap\´s pixels through the blue-noise mask matrix, This minimization brings the Fourier spectra of the selected key intensity levels as close as possible to the corresponding "blue noise" spectra. The continuity of the algorithm\´s behavior across the full range of intensity levels is achieved thanks to smooth interpolation between the distribution coefficients corresponding to key levels. The algorithm get the ideal bi-pattern with reasonable ordered statistic and blue-noise spectrum characteristic, and obtain the aesthetic feeling settle for people\´s vision.
