基于量子信号处理的数字半色调算法
Digital Halftoning Algorithm Based on Quantum Signal Processing
摘要
Abstract
A new halftoning method based on quantum signal processing is proposed for the digital halftoning technical. Firstly the normalized gray images are expressed as the form of quantum bit, then we make the quantum measurement with random obser-vation. The original image is collapsed into a binary image after measuring. The error between the binary image and the original image is calculated, and the product of the error and the adaptive feedback coefficient is used for image enhancement processing. Finally the halftone image is generated by the enhanced image using the traditional error diffusion algorithm. The simulation re-sults show that the method can reduce structural texture and increase the contrast of halftone image. It outperforms the convention-al digital halftone methods in subjective vision perception and objective evaluation index.关键词
