基于有效区域选取的变电压 X-射线图像融合
Multi-voltage X-ray image sequence fusion based on selection of valid region
摘要
Abstract
A key step is to extract valid information region in the fusion of multi-voltage X-ray image sequence for complicated components.To improve the self-adaption of extraction,a method is presented in this paper.In this paper,the valid informa-tion region is selected by the grey level interval,which is computed by the optimization of image quality evaluation model.The model is based on the histogram equalization and the grey level interval.Then,every valid region of images at different voltages is extracted and they are fused according their grey level transformation function.The fusion image contains completed struc-ture information of the component.The fusion experiment of a cylinder head shows the effectiveness of the presented method.关键词
