基于对应点匹配的眼球切片图像插值算法

图像插值是三维重建的一个关键步骤。针对眼球切片图像的特点,研究和分析了传统的图像插值方法,并在此基础上提出了一种改进的对应点匹配插值方法。先根据改进的对应点匹配准则在相邻层间建立点对点的对应关系,然后利用这些对应点进行插值,得到插值图像数据。实验结果表明,该算法能有效减少插值误差,获得令人满意的效果。

An Interpolation Algorithm of Eye Slice Images Based on Matching Corresponding Points

Image interpolation is one of key procedures for 3-D reconstruction.According to the characteristics of eye slice images,the traditional image interpolation methods are studied and analyzed.An improved interpolation algorithm based on matching corresponding points is presented.Firstly,the corresponding points are established between the points in neighboring slices based on improved points matching rules.Then these points are used to estimate interpolation image data.The experimental results show that the algorithm can decrease the interpolation error effectively and satisfactory experimental results are attained.
