Area of Science:

  • Computer Vision
  • Infrared Imaging
  • Signal Processing

Background:

  • Target tracking in Forward-Looking Infrared (FLIR) video sequences faces challenges including low signal-to-noise ratio (SNR), image blurring, partial occlusion, and limited texture information.
  • These limitations often result in missed targets or the tracking of non-target objects, compromising system performance.

Purpose of the Study:

  • To develop a novel and robust algorithm for target detection and tracking in FLIR video sequences.
  • To address the limitations of existing methods by combining image preprocessing with advanced correlation and matching techniques.

Main Methods:

  • A local-deviation-based image preprocessing technique was employed to suppress background noise and enhance target edge features.
  • A hybrid approach combining Fringe-Adjusted Joint Transform Correlation (FJTC) and Template Matching (TM) was developed for target detection and tracking.

  • The FJTC-TM algorithm leverages cross-correlation coefficients to compensate for FJTC's limitations in complex scenarios like target occlusion or background blending.

    • Main Results:

    • The proposed FJTC-TM algorithm demonstrated robust performance in real-life FLIR image sequences.
    • The integrated preprocessing and hybrid detection/tracking method effectively mitigated issues caused by low SNR, blurring, and occlusion.
    • The algorithm successfully improved target tracking accuracy compared to standalone methods.

    Conclusions:

    • The FJTC-TM algorithm offers a significant advancement in target tracking for FLIR imagery.
    • This novel approach provides a reliable solution for challenging surveillance and reconnaissance applications.
    • The combined FJTC and TM strategy enhances robustness and accuracy in complex, real-world scenarios.
