A flexible representation of quantum images for polynomial preparation, image compression, and processing operations

TL;DR: A constructive polynomial preparation for the FRQI state from an initial state, an algorithm for quantum image compression (QIC), and processing operations for quantum images are combined to build the whole process for Quantum image processing onFRQI.
Journal ArticleDOI

Watermarking and authentication of quantum images based on restricted geometric transformations

TL;DR: Simulation-based experimental results involving the classical (i.e. conventional or non-quantum) simulation of the input images, watermark signals, and quantum circuits yielded a 25% improvement in terms of overall watermark-embedding capacity and between 7% and 50.7% in the visible quality of the watermarked images in comparison with select digital watermarking methods for various pairs, thus, demonstrating both the feasibility and capabilities of the proposed WaQI scheme.

Strategies for designing geometric transformations on quantum images

TL;DR: Three design strategies for constructing new geometric transformations on quantum images from other transformations are proposed, providing high level tools to explore and analyze transformations which are necessary to build practical image processing applications on quantum computers.

Fast Geometric Transformations on Quantum Images

TL;DR: In this article, the complexity of the circuits is O(log 2 N) for two-point swapping, flip, co-ordinate swapping, and orthogonal rotations.
