    This study introduces new criteria for image gathering and processing, optimizing optical design with advanced algorithms. The research enhances machine vision by improving edge detection and reducing data needs, mimicking human visual processing.

    Area of Science:

    • Optics and Image Processing
    • Computational Vision
    • Machine Learning

    Background:

    • Traditional image gathering and processing methods often overlook aliasing, blurring, and noise.
    • Existing formulations do not fully integrate optical design with image-forming and edge-detection algorithms.

    Purpose of the Study:

    • To develop and apply information and fidelity criteria for assessing image gathering and processing.
    • To combine optical design principles with image-forming and edge-detection algorithms.
    • To improve machine vision systems by optimizing data preprocessing and transmission.

    Main Methods:

    • Formulation of information and fidelity criteria.
    • Analysis of the relationship between sampling passband, spatial response, and signal-to-noise ratio (SNR).
