[0046] The specific technical solutions of the present invention will be further described below in conjunction with the accompanying drawings.
[0047] The resolution of the original high-resolution remote sensing image processed by the method of the present invention is up to 6 meters, and the image size is 1292 columns × 2044 rows, and contains four wave bands, which are blue wave band (0.45-0.52 μm) and green wave band (0.52-0.59 μm). μm), red band (0.63-0.69μm), near-infrared band (0.77-0.89μm), radiation quantization level is 8bit, such as figure 2 shown. The target to be extracted is the human cultivation area.
[0048] Such as figure 1 As shown, the specific steps of the method for extracting the salient surface specific target in the remote sensing image of the present invention are as follows:
[0049] 1) According to the size of the specific target, the image is segmented at the optimal scale. In this embodiment, the Multiresolution Segmentation algorithm in Yika...
