    This study introduces an image-free target tracking method using discrete cosine transform and single-pixel detection. The novel approach significantly reduces sampling and enhances real-time tracking efficiency for fast-moving objects.

    Area of Science:

    • Optics and Photonics
    • Signal Processing
    • Computer Vision

    Background:

    • Traditional image-based target tracking suffers from low efficiency due to continuous image acquisition and post-processing.
    • Real-time tracking of fast-moving objects remains a challenge for conventional methods.

    Purpose of the Study:

    • To develop an efficient, image-free target tracking scheme for fast-moving objects.
    • To reduce sampling requirements and measurement time while maintaining high tracking accuracy.

    Main Methods:

    • Proposed an image-free tracking scheme utilizing discrete cosine transform (DCT) and single-pixel detection.
    • Implemented complementary modulation to minimize measurement noise.
    • Applied background subtraction to improve target contrast.

    Main Results:

    • Achieved tracking with a sampling ratio below 0.59% of the Nyquist-Shannon criterion.
    • Demonstrated high-speed tracking at 208 frames per second (fps) with 128x128 pixel resolution.
    • Maintained a tracking error of no more than one pixel in complex backgrounds.

    Conclusions:

    • The proposed image-free scheme significantly reduces measurement time and enhances tracking efficiency.
    • This technique offers a novel approach for real-time tracking of fast-moving targets.
    • The method proves effective even in complex background environments.
