Application of EM algorithm in problems of pattern recognition on satellite images

The using of Gabor function and texture features for pattern recognition in satellite images, principal component analysis (pca) and em-algorithm are discussed in this paper. Based on the presented in this article results of the experiment, the algorithm based on em-algorithm and Gabor wavelets demonstrated high quality of the result and low time characteristics. The novelty of the method under consideration is the use of the Gabor wavelet to isolate texture features in conjunction with the use of the em-algorithm for image segmentation and the pca algorithm to reduce the dimensionality of the feature space of the extracted images.
