In order to overcome the shortcomings of the traditional image classification based on spectral and texture, the authors propose an image classification method considering temporal features in this paper. Land use vector map in historical period was used as auxiliary data. The objects were extracted by image segmentation under the constraint of land use vector map. The land cover transition probability which represents temporal feature was calculated by iterative statistic method. The joint probability of object based on temporal feature was built after integrating the land cover transition probability into the traditional maximum posteriori probability. The image classification map was obtained by the maximum posteriori probability theory. The experimental results based on the QuickBird image show that the proposed method can improve the accuracy of the image classification result. Compared with things of the traditional classifier using spectral and texture features, the overall classification accuracy and kappa coefficient of the proposed method are increased by 9.8% and 17.9% respectively.
