摘要
为了解决量子灰度图像处理中量子图像的表示问题,利用量子态保存图像的灰度信息和位置信息,依据灰度图像灰度变化范围小的优势,提出并证明了一种量子灰度图像的存储表达式,而且在此表达式的基础上,提出了"量子指针"的概念。把量子指针作为图像像素灰度信息与位置信息联系的纽带,利用其双向性和子块性可使得量子灰度图像在存储及其他操作方面更为简单,方便,最后也验证了它的可行性。
In quantum gray-scale image processing,the storage in quantum states is the color information and the position information. According to the advantage of small range of the gray scale in a gray-scale image,this paper proposes and demonstrated a novel storage expression of quantum gray-scale image. Besides,based on the expression,a new concept of"quantum pointer"is put forward. Quantum pointer is the vinculum between the information of gray-scale and position of each pixel in quantum gray-scale images. The paper verifies the feasibility of the proposed quantum pointer and finds it made the storing and other operations of quantum gray-scale image simpler and more convenient with the properties of bi-direction and sub-block.
