Abstract:

针对多幅眼底图像拼接的问题,提出一种优化的多幅眼底图像拼接方法。该方法在基于特征的层次鲁棒估计方法完成两两图像初始配准的基础上,提出一种基于重叠区域的配准修正,得到两幅图像之间的良好配准;然后建立图像之间配准关系的无向图,并将配准图像中匹配特征的几何误差和相似度作为图中边的权值,通过计算关系图的最短路径,确定基准图像;再构造基于基准图像的直接约束和基于非基准图像的间接约束的多幅图像配准整体模型,用来生成多幅拼接图像。最后在图像融合部分,提出基于距离变换的多频带融合方法,消除拼接图像中的接缝,达到平滑融合效果。实验结果表明,该方法可有效消除多幅配准的累积误差,实现多幅眼底图像输入顺序无关性的精确配准和无缝拼接。
