[0059]The specific implementation manner and working principle of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0060] Such as figure 1 As shown, a remote sensing image building detection method based on multi-scale and multi-feature fusion is carried out according to the following steps:
[0061] S1: The size, position, and orientation of buildings in high-resolution remote sensing images vary greatly. It is difficult to detect buildings of different sizes from a single scale. Therefore, firstly, down-sample the high-resolution images. Get the image pyramid;
[0062]
[0063] Use the above Gaussian function to smooth the image, where W(p,q)=W(p)*W(q) represents a Gaussian convolution kernel with a length of 5, and (p,q) are the coordinates of the midpoint of the Gaussian convolution kernel , (i,j) is the coordinates of the midpoint of the image. Thus, an image sequence {ML, ML-1, . . . , M0} with decreas...
