[0018] Combine figure 1 , The present invention is based on the total variation-based adaptive infrared focal plane non-uniformity correction method, the specific steps include the following:
[0019] Step 1. Obtain the forward and backward gradient F from the original image according to the odd and even frame f (i,j), F b (i,j), namely
[0020] F f,y (i,j)=X(i,j)-X(i+1,j)
[0021] F f,x (i,j)=X(i,j)-X(i,j+1)
[0022] F b,y (i,j)=X(i,j)-X(i-1,y)
[0023] F b,x (i,j)=X(i,j)-X(i,j-1)
[0024] F f (i,j) is the forward gradient with the center coordinate of (i,j) in odd frames, F b (i,j) is the backward gradient with the center coordinate of (i,j) in the even frame, X(i,j) is the estimated value of the pixel correction with the center coordinate of (i,j), F f,x (i,j), F f,y (i, j) are the forward gradients in the x and y directions, respectively;
[0025] Among them, according to the different odd and even frames of the image sequence, the forward and backward gradient values are calcul...
