Selecting appropriate neighbor sets is crucial for accurate random field (RF) models in image analysis. This study proposes a method to identify optimal neighbor sets for autoregressive and Gauss-Markov models based on image correlation.

Area of Science:

  • Image analysis and modeling
  • Statistical signal processing
  • Computer vision

Background:

  • Random field (RF) models are essential tools for image modeling and analysis.
  • The performance of RF models heavily relies on the selection of neighbor sets, which define spatial interactions.
  • Current methods may not optimally select neighbor sets for specific RF model types.

Purpose of the Study:

  • To propose a novel procedure for selecting neighbor sets for simultaneous autoregressive and Gauss-Markov random field models.
  • To optimize the spatial interactions represented by RF models based on image characteristics.
  • To enhance the effectiveness of RF models in image analysis applications.

Main Methods:

  • Developed a procedure for identifying appropriate neighbor sets for RF models.

  • The selection process is based on the correlation structure of the image data.
  • Applied the method to simultaneous autoregressive and Gauss-Markov random field models.

    • Main Results:

    • Experimental results demonstrate the viability and effectiveness of the proposed neighbor set selection procedure.
    • The method successfully identifies neighbor sets that improve RF model performance.
    • Validated the approach on various image datasets.

    Conclusions:

    • The proposed method provides a systematic approach to neighbor set selection for RF models.
    • Optimizing neighbor sets based on image correlation significantly enhances model accuracy.
    • This work contributes to more robust and effective image modeling and analysis techniques.
