Embodiment Construction
[0106] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0107] like figure 1 As shown, the present invention designs an image fusion method based on wavelet directional correlation coefficient, uses wavelet transform to decompose the source image into low-frequency and high-frequency parts of different scales, and the low-frequency sub-band adopts the spatial frequency correlation coefficient based on cyclic shift sub-block Determined pixel point fusion rules; for each high-frequency sub-band according to the directional characteristics of the sub-band where it is located, the high-frequency coefficient is determined by using the normalized correlation coefficient difference between the regional energy and the gradient based on the directional characteristics.
[0108] Specific steps are as follows:
[0109] Step 001. The two images A and B to be fused are denoised and image...
