Detailed Documentation
This paper presents a SAR image segmentation method based on Markov Random Field (MRF). The approach employs the Maximum a Posteriori (MAP) probability criterion to segment SAR target slice images, with clustering analysis algorithms used for solution derivation. The method demonstrates high accuracy and robustness, effectively extracting target information from SAR images. Implementation typically involves defining neighborhood systems, modeling conditional probability distributions, and minimizing energy functions through iterative algorithms like Iterated Conditional Modes (ICM) or Graph Cuts. The technique offers strong applicability and extensibility, adaptable to various SAR image segmentation scenarios, thereby providing novel approaches for SAR image analysis and processing. Key algorithmic components include parameter estimation using Expectation-Maximization and spatial context modeling through clique potential functions.
