在计算机图像镶嵌中,两相邻图像间接缝的选择是个关键性步骤。常用的方法是根据某种误差准则来逐行(列)选择接边点。现有的误差准则中存在的问题是水平接边质量比垂直接边的质量差。本文提出用两维接边准则代替原有一维准则,使水平接边与垂直接边质量相当。对多波段彩色合成图像数字镶嵌,提出了在三组图像重叠区加权绝对灰差和图像上用两维准则选择寻找接边点的方法。取得了较好的结果。
In computer image mosaic, the choice of seam between two adjacent images is a crucial step. A commonly used method is to choose a tandem point row by row (column) based on some kind of error criterion. The existing problem in the error criterion is that the quality of the horizontal edge is worse than that of the vertical edge. This paper proposes to replace the original one-dimensional criterion with the two-dimensional edge-jointing criterion so that the quality of the horizontal edge and the vertical edge are equivalent. For the digital mosaic of multi-band color composite images, a method of finding the absolute gray difference between three groups of image overlap regions and selecting the two-dimensional criterion to find the edge points is proposed. Achieved good results.
