Embodiment 1
[0036] This embodiment provides a method for classifying and extracting surface water bodies, including:
[0037] Classifying all the pixels in the remote sensing image related to the surface water body into a feature space; the feature space is composed of a plurality of feature bands;
[0038] Selecting a pixel located at a corner point in the feature space as a feature sample, and forming a feature sample library;
[0039] Classify the pixels to be classified according to the surface object samples to obtain surface classification results;
[0040] The surface water body is extracted from the surface classification result.
[0041] The method for classifying and extracting surface water bodies provided in this embodiment will be described in detail below with reference to diagrams. see figure 1 , which is a schematic flowchart of an embodiment of a method for classifying and extracting surface water bodies. Such as figure 1 As shown, the surface water body classificati...
