摘　　要：等效厚度差异悬殊工件的变电压X射线图像序列经过融合后细节模糊,对比度降低。为此,本文提出了一种变电压X射线图像序列融合增强算法。首先用基于非锐化掩模的加权融合方法实现图像序列的融合,以提高融合图像的对比度,然后再利用基于金字塔变换的增强算法对融合图像进行增强。实验结果显示,X射线图像得到了显著增强。After fusion,detail blurs and contrast decreases for variable voltage X-ray image sequences of detected object with great difference in equivalent thickness.For this reason,this paper proposes an enhanced algorithm of variable voltage X-ray image sequence fusion.Firstly,the weighted fusion method based on non-sharp mask is used to realize the image sequence fusion to improve the contrast of the fused image,and then the enhanced algorithm based on pyramid transform is used to enhance the fused image.The experimental results show that the X-ray images are significantly enhanced.
