[0018] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.
[0019] Such as figure 1 As shown, the infrared image streak filtering method based on image layering includes the following steps:
[0020] S1. Divide the infrared image into a smooth layer image S and a noise layer image N.
[0021] In the step S1, an edge-preserving filter is used to divide the infrared image into a smooth layer image S and a noise layer image N.
[0022] S2. Apply one-dimensional local median filtering to each row of the noise layer image to obtain a preprocessed noise layer image N_O.
[0023] The expression of the noise layer image N_O of the preprocessing is:
[0024] N_O(x,y)=med(N(x-k:x+k,y))
[0025] In the formula, x represents the column coordinate, y represents the row coordinate, 2k+1 represents the window ...
