In this study, both traditional and quantum image processing methods are considered in order to highlight the boundaries of objects. For efficient encoding and processing of pixel intensities, the use of quantum ventilation, in particular the Hadamard transform, is being studied. Quantum algorithms can work with exponential acceleration compared to classical methods; this is especially important for working with large images. The study examines the influence of quantum transformations on the boundary determination process, as well as methods of amplitude permutations to obtain data on edge elements. The superposition and entanglement of qubits have shown to improve the performance and accuracy of the algorithm when processing multiple boundaries simultaneously. It has now been established that quantum computation of intensity differences between neighboring pixels plays an important role in boundary detection. Experiments with 64x64 pixel images have shown that the quantum algorithm performs well in image processing tasks. It has been substantiated that the use of the quantum approach increases processing speed and reduces computational costs. A quantum circuit of the algorithm with its main transformation stages is presented. In general, pathways for further optimization of the algorithm have been developed, which include reducing the number of qubits and adapting it for more complex images.
Quantum image computing has attracted attention due to its vast storage and faster processing of image data than classical computers. Although classical computing power has grown substantially in the last decade, its abilities have plateaued, struggling to meet the needs of huge datasets. Quantum computers, on the other hand, take advantage of unique qualities like quantum parallelism, superposition, and entanglement to provide faster solutions to complicated problems. Managing huge image data in classical systems necessitates significant memory and hardware resources, which makes quantum computing a possible alternative. Several approaches have arisen for encoding and compressing classical images in the quantum processor. However, one of the most significant limitations is the complexity of quantum state preparation, which translates pixel coordinates to corresponding quantum circuits. Current approaches for representing large-scale images require a huge number of quantum resources including qubit, and qubit connection, which presents significant hurdles. Therefore, this article aims to overview the pixel intensity and state preparation circuit that needs fewer connections, i.e., quantum gates to represent quantum image data, and then explore and design effective compression and processing methods for medium and high-resolution images. This work specializes in emerging quantum models’ potential for enhancing image representation and compression capabilities. It also conducts a comprehensive study of quantum image representation and compression techniques, categorizing existing methods by grayscale and color image types and evaluating their methods, strengths, and limitations. It focuses on crucial difficulties, such as high qubit requirements and complex state preparation, that limit scalability for huge images. This paper also assesses each model’s compression efficacy, which will help future research focus on efficient circuit designs with lower complexity for medium to high-resolution images. It is an essential reference for advancing quantum image processing research since it provides a systematic framework for evaluating quantum image compression and representation algorithms.
