[Abstract]
The segmentation of SAR target chip image is an important process for target recognition based on SAR image. Utilizing MRF (Markov Random Field) model to introduce the pixel's local context information, a quite accurate segmentation of SAR target chip image is realized. By statistical analysis of SAR target chip image for choosing the initial value of the segmentation method, the efficiency of the algorithm is improved greatly. Compared with other segmentation algorithms, our algorithm improves greatly the segmentation speed and accuracy .
