Image fusion is widely applied in image processing area.On the basis of introducing the technology of multi-scale wavelet analysis,different parts of image are wavelet decomposed,quadratic moment and information entropy of corresponding image's wavelet coefficients is used to identify definition and information amount of image.Required image definition is gotten by wavelet reverse analyzing and reconstructing of image with a specific processing criteria.This algorithm is proved to be viable by experiments and clear image is gained to identify detail and defect effectively.%图像融合是信息处理在图像领域中的一个重要应用.在引入多尺度小波分析的基础上,通过对图像各个部分进行多尺度小波分解,建立小波系数矩阵二阶矩以标志对应相关部分的图像信息的清晰度,并通过图像信息熵以标志图像信息量.通过特定选择机制进行小波逆向分解与图像重建,最终获得符合信息处理要求的清晰融合结果.编程实验证明了本方法的有效性和可行性,使芯片图像的细节和缺陷等能够得到很好的展现.
