摘要
分析了图像拼接处理中导致线条结构不连贯的原因,提出了一种引入线条结构连贯性约束的优化拼接方法。其基本思路是自动识别并定位图像边缘处的线条结构,并求出两幅邻接图像间的线条结构对应关系,利用这些对应关系对拼接图像进行局部修正。实验结果表明,该方法适用于具有明显线条特征的图像,能够有效改善拼接的局部细节。
Based on the analysis of the discontinuity in the switch lines in image mosaic, we propose a novel optimization algorithm of switch line adjustment based on the continuity restriction of line structures. The processing includes： automatic extraction of linear structures at the border of the switched images ; calculate the correspondence between the linear structures in adjacent images; adjust switch lines based on the continuity restriction of linear structures. The exporiments demonstrated that the proposed algorithm can improve the switch line of image mosaic.
