    Area of Science:

    • Optics and Photonics
    • Image Processing
    • Computational Imaging

    Background:

    • Fourier single-pixel imaging (FSI) is promising for compressive imaging.
    • Low sampling ratios in FSI can cause ringing artifacts, degrading image fidelity.
    • Existing methods struggle to preserve fine details in reconstructed images.

    Purpose of the Study:

    • To introduce Vector guided Fourier single-pixel imaging (V-FSI) to mitigate artifacts in low-sampling-ratio FSI.
    • To improve the fidelity and detail preservation of reconstructed images.
    • To enhance the performance of compressive imaging techniques.

    Main Methods:

    • Analysis of statistical properties within the edge vector field of low-sampling-ratio images.
    • Design of a tailored sampling map to capture crucial high-frequency components.
    • Implementation and experimental validation of the V-FSI technique.

    Main Results:

    • V-FSI significantly enhances image quality compared to traditional FSI.
    • The method effectively reduces ringing artifacts associated with low sampling ratios.
    • Exceptional preservation of object details, particularly for periodic and directional features, was observed.

    Conclusions:

    • V-FSI offers a superior approach for compressive imaging with low sampling ratios.
    • The technique demonstrates remarkable effectiveness in reconstructing high-fidelity images.
    • V-FSI shows significant potential for applications requiring detailed image reconstruction from limited data.
