Feature extraction is the most fundamental and important problem in satellite forest image recognition problem, but how to extract the feature is an important step towards solving recognition problems. The forest image features commonly consist of visual feature, statistical feature, transform field feature, and algebraic feature. The paper uses SPOT remote sensing forest images as samples, SVD (singular value decomposition) and GLCM (gray-level co- occurrence matrix) as the methods of feature extraction, it also compares and analyzes these two methods. The results of comparison show that GLCM is more effective in describing the visual feature and SVD in describing the internal feature. Forest image statistical feature can describe the image macroscopic features, such as the texture feature shape feature, etc. But SVD can describe the image internal features. The SVD spectral features synthesize the features of image at the pixel level. The combination of the two methods can be more effective in the forest image recognition and classification. We use both SVD and GLCM to extract remote sensing forest image features, and by the combination of these two methods we have got a better recognition of the ground surface forest of remote sensing images than before. Our word shows that the forest recognition rate reaches up to 95%.
