Embodiment 1
[0099] A method for detecting snow mountains based on infrared remote sensing images provided by a preferred embodiment of the present invention includes the following steps:
[0100] Step 1: Read the infrared remote sensing snow mountain image f to be detected 0 (x,y), such as figure 2 shown;
[0101] Step 2: Infrared remote sensing snow mountain image f 0 (x, y) is preprocessed to obtain the preprocessed image f after denoising and contrast enhancement 2 (x,y);
[0102] Step 2.1: Infrared remote sensing snow mountain image f 0 (x, y) performs median filtering processing, sorts the pixels in the area of each pixel in the image according to the gray value, and takes the median of the sorting results as the gray value of the pixel after filtering:
[0103]
[0104] Among them, S xy is the field of point (x, y), usually take a square field of 3×3 pixels around point (x, y), g(s, t) is the gray value at (s, t) in the field, according to the above formula , perform th...
