Zhenzhong Chen, Ye Hu, Yingxue Zhang · IEEE Transactions on Geoscience and Remote Sensing · 2019
Image compression is essential for remote sensing due to the large volume of produced remote sensing imagery and system's limited transmission or storage capacity. As one of the most important applications, classification might be affected due to the introduced distortion during compression. Hence, we perform a quantitative study on the effects of compression on remote sensing image classification and propose a method to estimate the remote sensing image classification accuracy based on fractal analysis. Multiscale feature extraction is performed and a multiple kernel learning approach is proposed accordingly. The experimental results on our established database indicate that the classification accuracy predicted by our method exhibits high consistency with the ground truth and our method shows its superiority when compared with other classical reference algorithms.
