Embodiment Construction
[0051] Refer below figure 1 , the implementation process of the present invention will be described in detail with reference to the embodiments.
[0052] In the embodiment of the present invention, two remote sensing images captured at the same place at different times are input first; in the embodiment of the present invention, the TM image captured by the landsat5 satellite in Hebei Province on April 6, 2009 and the TM image captured by the landsat7 satellite in 2003 are used. The ETM image taken at the corresponding location on April 30, in which the size of the TM image is 400×400×6, the size of the ETM image is 400×400×6, and the spatial resolution is 30m. The specific implementation steps are as follows:
[0053] Step 1. Two remote sensing images of different phases: Phase 1 X, Phase 2 Y;
[0054] Step 2. Calculate the difference map DI, and use the ERS (Entropy Rate Superpixel) method to perform superpixel segmentation on the difference map DI to obtain N superpixels...
