    This study presents a novel algorithm using support vector regression (SVR) for image restoration. The SVR method demonstrates robust performance in blind deconvolution, even with unknown blur types and noise levels.

    Area of Science:

    • Computer Vision
    • Image Processing
    • Machine Learning

    Background:

    • Image restoration is crucial for enhancing visual data quality.
    • Blind deconvolution, which estimates the original image without prior knowledge of the blur, is a challenging problem.
    • Existing methods often struggle with unknown blur characteristics and noise.

    Purpose of the Study:

    • To introduce a new algorithm for noisy and blurred image restoration.
    • To evaluate the effectiveness of support vector regression (SVR) for blind image deconvolution.

    Main Methods:

    • Developed a novel image restoration algorithm.
    • Utilized support vector regression (SVR) as the core technique.
    • Tested the algorithm in blind deconvolution scenarios with unknown point spread function (PSF) and noise levels.

    Main Results:

    • The proposed SVR-based algorithm effectively restores noisy and blurred images.
    • Demonstrated robust performance in blind image deconvolution tasks.
    • Showcased successful restoration even when blur types, PSF support, and noise levels were unknown.

    Conclusions:

    • Support vector regression (SVR) offers a robust solution for blind image deconvolution.
    • The developed algorithm provides a promising approach for challenging image restoration problems.
    • The SVR method is effective in handling unknown image degradation parameters.
