Embodiment 1
[0077] Such as figure 1 As shown, this embodiment provides an infrared imaging river channel detection method based on neighborhood intensity texture coding, including the following steps:
[0078] S1: Acquisition and input of infrared images containing river I 1 ,Such as figure 2 shown;
[0079] S2: To infrared image I 1 Neighborhood intensity texture coding is performed to obtain the texture image I 2 ,Such as image 3 As shown, it specifically includes the following steps:
[0080] S2.1: Determine the neighborhood and number of the encoded pixel:
[0081] Set infrared image I 1 The size is M×N, and the encoded pixel I 1 (u,v) is G c , where u=2,3,...,M-1, v=2,3,...,N-1; for the encoded pixel G c The surrounding 3×3 neighborhoods are numbered, and the numbering rule is: the pixel G to be encoded c The number of adjacent pixels on the right is G 1 , then with G 1 As the starting point, the adjacent pixels are numbered as G in the clockwise direction 2 , G 3 , ...
