A comprehensive review on quantum image processing entitled, "Quantum image processing: A review of advances in its security technologies", has been published in World-Scientific-International Journal of Quantum Information by Dr. Fei Yan, a young researcher in Changchun University of Science and Technology.
Quantum image processing (QIP) is an upcoming sub-discipline that aims to extend standard image processing tasks and operations to the quantum computing framework. This emerging sub-discipline mainly focuses on employing quantum computing technologies in order to capture, manipulate, and recover quantum images in a wide range of formats and also for varied purposes.
The existence of a few surprising properties, such as parallelism and entanglement, inherent to quantum computation, has led to the anticipation that QIP technologies will offer performances and capabilities that are, up till now, unrivalled by their standard equivalents. These improvements could be in terms of minimal storage requirements, guaranteed security, and computing speed, etc.
This study presents an overview of the improvements made in QIP comprising of the operations realizable on them, the image representations, and likely algorithms and protocols for their applications. The authors of the study specifically focus on latest progresses on QIP-based security technologies including quantum image steganography, quantum image encryption, and quantum watermarking.
The study aims at offering a concise and yet adequate image compendium of the developments brought about in the QIP sub-area. This effort is expected to inspire further interest aimed at the pursuit of more enhanced algorithms and experimental validations for the existing technologies and extensions to various other domains.
The objectives of the discussions presented towards the end of this study are twofold. The first objective targets researchers already working in this area, and enumerates some of the open questions emanating from the published literature. The second objective mainly focuses on the upcoming researchers who may be interested in pursuing advanced research in the area. In this, the author focuses on detailing a few considerations that are supposed to guide them in their pursuits. Hopefully, the study delivers a compendium of relevant literature required to invigorate more advanced research in the area.
