【摘要】：针对复杂背景下遥感影像镶嵌中快速自动生成均匀分隔重叠区域且形态美观的几何拼接线,提出了一种基于图像解析的沿重叠区域骨架的几何拼接线自动生成算法。首先顾及复杂背景值区域标记待镶嵌影像的不同类型区域;然后每一处待处理重叠区域被认为是一个图像对象,迭代搜索图像对象的轮廓线,并按指定规则对轮廓线逐像素标记,直至重叠区域中不存在这样的待处理区域;最后基于4邻域搜索标记沿骨架的几何拼接线。实验结果表明,即使顾及背景值影像重叠区域为复杂多边形时,该算法也能快速自动生成美观的几何拼接线。算法鲁棒性优于基于图形解析的方法。
[Abstract]:In view of the fast and automatic generation of geometric stitching lines in remote sensing image mosaics with uniform separation of overlapped regions and beautiful morphology, an algorithm for automatically generating geometric stitching lines along the framework of overlapping regions based on image analysis is proposed. The complex background value region is taken into account to mark different types of regions of the image to be embedded; then each of the overlapped areas to be processed is considered to be an image object, and the contour lines of the image object are searched iteratively. The contour lines are marked pixel by pixel according to the specified rules until there is no such unprocessed region in the overlapped region. Finally the geometric splicing line along the skeleton is searched based on the 4-neighborhood search marker. The experimental results show that the algorithm can automatically generate beautiful geometric stitching lines even if the overlapped region of background image is considered as a complex polygon. The robustness of the algorithm is superior to the method based on graph analysis.
