Embodiment Construction
[0024] When applying multi-scale analysis methods to image fusion, the fusion rules play a vital role in the fusion algorithm. The conventional average or the rule with the largest modulus value will lead to a decrease in the quality of the fusion image. The focus evaluation operator comes from the field of multi-focus image fusion and is used to measure the degree of change of pixels. For a well-focused image region, the metric value of the focus evaluation operator will be relatively high. Considering the rich details of the visible light image, the outstanding characteristics of the infrared image target, and the sub-band of the image in the Curvelet domain can also be regarded as an image, and there is a change in amplitude, so using the focus evaluation operator to select the transformation domain coefficient of the fused image is reasonable. The present invention introduces the focus evaluation operator into the Curvelet domain, proposes a fusion method based on the foc...
