摘要
为了提高图像增强的质量,采用量子算法。首先基于高斯核密度函数对量子点采集,获得最佳核宽;然后在最佳核宽范围内,通过量子比特对图像像素描述,找到像素之间比特位的不同,完成像素之间的对比;接着转换矩阵对量子态输出和输入描述,确定双量子比特态最佳概率;最后给出实现增强图像算法过程。实验仿真显示本文算法增强图像清晰,评价质量函数QMF较好,消耗时间少。
In order to improve the quality of image enhancement,quantum algorithm was proposed in this paper.Firstly,quantum dot was collected based on gauss kernel density function,and the optimal kernel width was obtained.Secondly,Image pixel was described by quantum bit in optimal kernel width,and bit was found between different pixels.Thirdly,Transfer matrix was described output and input of quantum state,which determines the best two quantum bit state probability,and implementation of image enhancement algorithm was given.Simulation results showed that the proposed algorithm enhances image quality effect,and the QMF is better and time is less.
