多尺度多特征融合的高分辨率遥感影像变化检测

Change Detection of High Resolution Remote Sensing Images on Multi-scale and Multi-Feature Fusion

针对高分辨率遥感影像变化检测方法中多特征的利用,以及对尺度变化敏感的问题,提出了一种多尺度多特征融合的检测方法。首先利用小波变换对两遥感影像进行多尺度分解,然后分别提取每一尺度影像的特征,对不同尺度下的同一特征进行融合检测,最后将多尺度多特征检测结果进行融合,得到最终检测结果。实验结果表明,本文方法充分考虑到了多尺度性和多特征贡献的差异,有效地提高了高分辨率遥感影像变化检测结果的准确性和完整性。

Aiming at using multi-feature and sensitive of high resolution remote Sensing Images to scale change during change detection,this paper proposes a new change detection algorithm for remote sensing images based on multi-scale and multi-Feature fusion.First,wavelet transform is used to decompose two images,and then to extract the images features of every scale,and fuse the same feature of different scale to realize change detection.Finally,detection results of multi-scale for multi-feature are fused to get the final change detection results.The experimental results show that the new method fully considers different contribution of multi-scale and multi-feature,and improves the accuracy and completeness of the change detection effectively.
