چکیده
The development of convolution neural networks (CNNs) has become a significant means to solve the problem remote sensing scene image classification. However, well-performing CNNs generally have high complexity and are prone overfitting. To handle above problem, we present new classification approach using an mmsCNN–HMM combined model with stacking ensemble mechanism in this paper. First all, modified multi-scale network (mmsCNN) is proposed extract structural features, which lightweight structure can avoid computational complexity. Then, utilize hidden Markov (HMM) mine context information extracted features whole sample image. For different categories images, corresponding HMM trained all HMMs form group. In addition, our based on learning scheme, preliminary predicted values generated by group used extreme gradient boosting (XGBoost) generate final prediction. This integrates multiple models make decisions together, effectively prevent overfitting while ensuring accuracy. Finally, XGBoost conducts category paper, six most widely datasets, UCM, RSSCN, SIRI-WHU, WHU-RS, AID, NWPU, selected carry out kinds experiments. numerical experiments verify that shows more important advantages than advanced approaches.

An ensemble learning method for scene classification based on Hidden Markov Model image representation
Low level images representation in feature space performs poorly for classification with high accuracy since this level of representation is not able to project images into the discriminative feature space. In this work, we propose an efficient image representation model for classification. First we apply Hidden Markov Model (HMM) on ordered grids represented by different type of image descript...
