摘　　要：为了解决量子图像处理中的图像增强问题,提出了一种基于灰度级-彩色变换法的量子图像伪彩色编码方法。基于通用量子图像表示(GQIR)模型,对热金属码分段函数进行量子化,并给出了该算法实现的量子线路图,该量子线路设计分为量子R变换器、量子G变换器和量子B变换器三部分,总的量子线路图所用基本量子门数为2947。相比于经典伪彩色编码,量子图像伪彩色编码基于量子态的叠加性和相干性,实现了空间复杂度和时间复杂度的指数级降低。仿真实验结果表明该算法具有可行性。In order to solve the problem of image enhancement in quantum image processing,a quantum image pseudo color coding method based on gray level-color transformation method is proposed.Based on the generalized quantum image representation(GQIR)model,the hot metal code segment function is quantized,and the quantum circuit diagram of the algorithm is given.The quantum circuit design is divided into three parts:quantum R converter,quantum G converter and quantum B converter,and the number of basic quantum gates used in the total quantum circuit diagram is 2947.Compared with classical pseudo color coding,quantum image pseudo color coding is based on the superposition and coherence of quantum states,which can reduce the spatial and temporal complexity exponentially.The simulation results show that the algorithm is feasible.
