摘要：讨论了医学影像图像处理中插值运算的数学模型,运用MATLAB平台对最邻近点插值、双线性插值和双三次插值等三种模型对医学影像图像增强的实现,从算法流程和程序设计方面进行了仿真研究,探讨了双三次插值克服了最邻近点插值、双线性插值等两种算法的缺陷,提高计算精度,但运算量大.双线性插值法使图像更光滑,但轮廓模糊.最邻近点插值法使插值生成的医学影像图像灰度值不连续,仿真结果表明分析的正确性.
The mathematical model of interpolation operation in medical image processing is discussed,and using MATLAB platform for the three model of the adjacent point interpolation,the bilinear interpolation and double three times,the implementation of medical image enhancement processes has carried on the simulation research from procedures of the algorithm and designed programmer.Then discusses the double three interpolation overcame the defect of two algorithms of the adjacent point interpolation and bilinear interpolation,and improves the calculation accuracy,but the computation is big.Bilinear interpolation method makes the image more smooth,but hazy outline.Nearest point interpolation method makes interpolation medical image grey discontinuous value.Finally,the experiment proved that the analysis is correct.
