In image and multimedia processing using quantum information processing, establishing methods for data compression and image quality assessment (QIQA) is a critical challenge. In our previous study, we proposed a data compression method for 360-degree camera images using quantum information and computer science; however, a concrete investigation into image quality assessment remained an unaddressed issue. Furthermore, most conventional QIQA studies utilizing representation models such as FRQI and NEQR to map images into quantum states have been limited to verification using small-scale toy images. Naive application to realistic high-resolution still images, such as high-definition (HD) quality, is challenging due to resource constraints, specifically the explosive increase in the required number of qubits and multi-controlled gates. To address this, this study investigates a realistic classical-quantum hybrid image quality assessment method that incorporates patch division and region of interest (ROI) sampling via classical image processing. The proposed method utilizes techniques such as the Swap Test to detect similarity directly within the quantum state without decoding the image back into classical space. Through quantitative comparative experiments using natural images, 3D computer graphics (3DCG), and 360-degree camera images, we clarify how differences in representation models—specifically FRQI, which represents color information via phase, and NEQR, which uses digital bitstrings—affect the detection sensitivity to image quality degradation. Based on these findings, we discuss the ideal approach for optimal quantum image quality assessment metrics. |
