我们定义了一个多分辨率样条技术结合成一个更大的图像马赛克两个或更多的图像。在这个过程中，要样条的图像首先被分解成一组带通滤波的分量图像。接着，将每个空间频带中的分量图像组装成对应的带通马赛克。在该步骤中，使用过渡区内的加权平均值来连接分量图像，该过渡区的大小与带中表示的波长成比例。最后，将这些带通拼接图像相加以获得期望的图像拼接。以这种方式，样条与图像本身内的特征的比例相匹配。当粗糙特征出现在边界附近时，这些特征在相对较大的距离上逐渐混合，而不会模糊或以其他方式降低边界附近的更精细图像细节。
We define a multiresolution spline technique for combining two or more images into a larger image mosaic. In this procedure, the images to be splined are first decomposed into a set of band-pass filtered component images. Next, the component images in each spatial frequency band are assembled into a corresponding band-pass mosaic. In this step, component images are joined using a weighted average within a transition zone which is proportional in size to the wave lengths represented in the band. Finally, these band-pass mosaic images are summed to obtain the desired image mosaic. In this way, the spline is matched to the scale of features within the images themselves. When coarse features occur near borders, these are blended gradually over a relatively large distance without blurring or otherwise degrading finer image details in the neighborhood of the border.
