Embodiment 1
[0025] Such as figure 2 As shown, the present embodiment is A for the infrared sequence image t (t=1...n) perform the following processing:
[0026] The first step: Use the GBVS algorithm to process the infrared sequence image A t Perform significance analysis to obtain the significance area B t , the specific steps include:
[0027] 1.1) Define sequence image A t Two pixel points m of the feature map 1 (i 1 , j 1 ) and m 2 (i 2 , j 2 ) difference:
[0028] Among them: M f (·) is the pixel in the feature map.
[0029] 1.2) After obtaining the difference between any two points in the image, a fully connected graph is constructed. Each vertex in the graph represents a pixel, and each edge represents the weight between two pixel points, namely Where: σ is the scale factor, m 1 (i 1 , j 1 ) and m 2 (i 2 , j 2 ) is two pixels;
[0030] 1.3) Obtain the significant region after normalizing all the weights.
[0031] The second step: using the improved SSIM alg...
