    A novel spatial-encoding scheme enables one-step optical hit-miss transform (HMT) implementation. This method also supports rank-order HMT for improved performance in noisy conditions, as confirmed by simulations and experiments.

    Area of Science:

    • Image processing
    • Optical computing
    • Computer vision

    Background:

    • The optical hit-miss transform (HMT) is a fundamental tool in image processing for shape detection.
    • Traditional HMT implementations can be complex and computationally intensive.
    • Robustness to noise and clutter is crucial for real-world applications.

    Purpose of the Study:

    • To introduce a new spatial-encoding scheme for efficient optical HMT.
    • To demonstrate the scheme's capability for one-step HMT implementation.
    • To validate the scheme's applicability to rank-order HMT for enhanced noise resilience.

    Main Methods:

    • Development of a spatial-encoding technique for optical HMT.
    • Implementation of a one-step HMT process using the proposed scheme.
