Beamer：带有图像的多个块 - 行垂直居中

Question

我有一张包含多个 s 的幻灯片block，每个 s 位于单独的 中column。每个块应包含两个相互重叠的图像。在我的用例中，这些是tikzpictures，但在这里我只使用includegraphics。

我想确保这些图像垂直居中，就像在矩阵中一样。如果您可以确保所有图像具有相同的大小，那么这种方法非常有用。但我不知道如何将不同大小的图像垂直居中在单独的块之间。

有什么想法吗？

另外，如何确保blocks 的高度相同？我尝试使用minipage，如建议的那样这里，但这会导致我的tikzpictures 产生一些意想不到的影响。
