[0080] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.
[0081] Texture refers to the texture (smooth, rough, delicate, etc.) of the surface of the object on the image, and is generally divided into different levels by smoothness / roughness. Texture is not only dependent on surface features, but also related to the angle of light, which is a changing value. Image texture is a visual feature that reflects the homogeneity phenomenon in the image, and it reflects the slow-changing or periodic-changing surface structure organization and arrangement properties of the object surface. Remote sensing image textures generally correspond to the corresponding surface object types. The basic idea of the present invention is to construct texture symbols with special semantic connotations (such as figure 1 As shown), o...
