Suppressing noisy features with quantum filters for efficient encoded images with high signal to noise ratios

Image processing is fundamental in computer vision and imaging research[1,2].Most image processing algorithms rely on Fourier transform.It is well-known that quantum Fourier transform(QFT)offers exponential speedup compared to their classical counterpart and serves as a crucial component in quantum algorithms such as Shor's factoring algorithm[3]and the HHL algorithm[4]to realize exponential speedup.
