Fault-tolerant quantum algorithm for dual-threshold image segmentation

Abstract The intrinsic high parallelism and entanglement characteristics of quantum computing have made image processing techniques a focus great interest. One the most widely used in is segmentation, which one their basic forms can be carried out using thresholding algorithms. In this paper, fault-tolerant dual-threshold algorithm has been proposed. This built only Clifford+ T gates for compatibility with error detection correction codes. Because implementation much higher cost than other gates, our on reducing number these gates. allowed adding noise tolerance, computational reduction, fault tolerance to state-of-the-art segmentation circuits. Since involves comparison operation, as part work we implemented two full comparator These circuits optimize metrics -count -depth respect best circuit comparators currently available literature.
