Embodiment Construction
[0055] The present invention proposes a multi-scale level set SAR image change detection method based on wavelet decomposition, which is characterized by: (1) firstly, the logarithmic ratio operation operator is used for two registered SAR images of the same area with different phases Make a difference map; (2) Perform multi-layer wavelet decomposition on the difference map by stationary wavelet decomposition (SWT) to obtain images with different resolutions; (3) Preliminarily segment low-resolution images by level set algorithm, and the obtained The outline of the segmented image is used as the initialization curve of the level set algorithm for the higher resolution image; (4) Follow step (3) layer by layer until the level set segmentation of the original high resolution image is performed to obtain the final segmented image.
[0056] Such as figure 1 shown.
