Embodiment Construction
[0025] In the millimeter-wave original image processed by the present invention, low-radiation suspicious targets such as knives and guns are dark areas, and high-radiation targets such as gasoline are bright areas. However, in the final fused image, suspicious targets are all represented by bright areas.
[0026] 1. Fusion algorithm for dark suspicious target areas of millimeter wave images and visible light images
[0027] Such as figure 1 As shown in (a), the fusion algorithm of the dark suspicious target area of the millimeter-wave image and the visible light image of the present invention includes:
[0028] In the first step, wavelet decomposition is performed on the millimeter-wave image and the visible light image to obtain their low-frequency coefficient matrix and high-frequency coefficient matrix respectively. Suppose the millimeter wave image is A, the visible light image is B, and the fusion image is F. Perform two-dimensional discrete wavelet transform on the...
