Embodiment Construction

[0020] Below in conjunction with accompanying drawing, the present invention is further described: a kind of quantum image staggering method based on NEQR expression, it is characterized in that: first, utilize NEQR expression to compile quantum image, NEQR expression is obtained by the basic state of quantum sequence The gray value of the pixel is stored. Therefore, the storage of the image in the quantum system is realized by two entangled quantum sequences, which respectively represent the gray level information and position information of the pixel. The definition is as follows:

[0021]

[0022] in represents a size of , the grayscale range is NEQR Quantum Image, Represents the position information of pixels in the image, while Represents the color information of the corresponding pixel, which is represented by a quantum sequence containing q qubits, namely ,in, is the fundamental state of the qubit or .

[0023] For the miscutting operation of NEQR qu...

Abstract

The invention relates to a quantum image shearing method based on an NEQR expression. The method is characterized in that an NEQR expression is used to compile a quantum image, the NEQR expression stores a gray value of a pixel through a basic state of a quantum sequence, therefore, image storage in a quantum system is realized through two tangled quantum sequences which express gray scale information and position information of a pixel, and a shearing operation of an NEQR quantum image can be divided into x axis shearing and y axis shearing; when the quantum image is shorn along an x axis, a translation amount of each row of pixels in the image along the x axis forms a positive correlation relationship with a y axis coordinate value of the row of pixels; and a quantum multiplier is used to calculate the translation amount of each row of the pixels in the quantum image during the shearing operation, and then, through a quantum interpolation operation, the translation amount is converted into an integer, and finally, a quantum adder is used to acquire position information of the quantum image after the shearing operation.

Description

technical field [0001] The invention relates to a quantum image staggering method based on NEQR expression, which is a basic operation of quantum image processing and belongs to the technical field of computer image processing. Background technique [0002] Image staggering is one of the basic operations in the field of classical computer image processing. It can make the geometric decomposition of images simple, fast and efficient, so it is widely used in many image processing algorithms. In recent years, with the development of quantum computing and quantum information technology, quantum image processing has received extensive attention, but the research on quantum image stagger operation is still blank. A quantum image can be represented by a variety of quantum expressions, NEQR (Novel Enhanced Quantum Representation) expression is one of them. The invention realizes the staggered operation of the NEQR quantum image through the exploration of the staggered matrix, and t...
