[0033] figure 1 is the basic flow of the algorithm.
[0034] A method for suppressing infrared image noise of enhanced details, said method comprising the following steps:
[0035] 1) Obtain the original infrared image P 0 ;
[0036] 2) Extract and strengthen the edge information in the original image to obtain an image P with edge information 1 ;
[0037] 3) Classify the image noise and set the threshold T, T h and T l ;
[0038] 4) Calculate with pixels in a 5×5 area, when the value of the center point in the 5×5 area exceeds the threshold T after processing h or below the threshold T l , it is identified as salt and pepper noise. When the total number of identified salt and pepper noise points in this area exceeds the set threshold T, the original image P 0 In this area, a separate filtering process is performed to obtain the processed image P 2 ;
[0039] 5) The remaining areas are identified as Gaussian noise, and the image P 1 Perform filtering processing to ...
