Problems solved by technology

[0006] The present invention aims at the deficiency that the traditional Gaussian mixture model cannot detect the change of the background in time, and the infrared target obtained through its detection contains false contours and is difficult to be accurately identified, and proposes an infrared moving target detection method based on structural similarity and saliency analysis and The system uses the watershed algorithm combined with the spatial information representing the discrete pixels of the target area to obtain a closed area, and then eliminates the ghost through the segmentation algorithm based on PCNN (Pulse Coupled Neural Network, Pulse Coupled Neural Network), and finally detects the complete infrared moving target. In this way, the foreground target can be better extracted, with better effect and stronger robustness.

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...
