字幕分割图像对齐中的矩阵

Question

我试图添加一些矩阵来显示同一图像上的卷积变换，但其中一个矩阵是 5x5，其他的是 3x3。问题是我无法保持图像完美对齐。

編輯：

以下是代码：

\documentclass{article}

\usepackage{graphicx}
\usepackage{subcaption}
\usepackage{amsmath}


\begin{document} 

\begin{figure}[htb!]
\centering
\begin{subfigure}[b]{0.45\textwidth}
    \centering
    \includegraphics[width=\textwidth]{figs/random.eps}
    \caption[Network2]%
    {{\small $\left(\begin{smallmatrix}1&0&1&0&1\\0&1&0&1&0\\1&0&-4&0&1\\0&1&0&1&0\\1&0&1&0&1\end{smallmatrix}\right)$}}    
    \label{fig:rand}
\end{subfigure}
\hfill
\begin{subfigure}[b]{0.45\textwidth}  
    \centering 
    \includegraphics[width=\textwidth]{figs/sharpen.eps}
    \caption[]%
    {{\small $\left(\begin{smallmatrix}0&-1&0\\-1&5&-1\\0&-1&0\end{smallmatrix}\right)$}}    
    \label{fig:sharpen}
\end{subfigure}
\vskip\baselineskip
\begin{subfigure}[b]{0.45\textwidth}   
    \centering 
    \includegraphics[width=\textwidth]{figs/edge_5.eps}
    \caption[]%
    {{\small $\left(\begin{smallmatrix}1&0&-1\\0&0&0\\-1&0&0\end{smallmatrix}\right)$}}    
    \label{fig:edge_5}
\end{subfigure}
\quad
\begin{subfigure}[b]{0.45\textwidth}   
    \centering 
    \includegraphics[width=\textwidth]{figs/edge_8.eps}
    \caption[]%
    {{\small $\left(\begin{smallmatrix}-1&-1&-1\\-1&8&-1\\-1&-1&-1\end{smallmatrix}\right)$}}    
    \label{fig:mean and std of net44}
\end{subfigure}
\caption[ Transformation of original image]
{\small Several convolution transformation of the original image. Each kernel gives a different configuration} 
\label{fig:edge_8}
\end{figure}

\end{document}

结果：

我应该怎么办？

问候！

• 如果图像有不同的高度，但您希望以相同的高度显示，则定义它们的高度：

    \begin{subfigure}[t]{0.45\textwidth}
        \includegraphics[width=\textwidth, height=44mm]{figs/random.eps}
        \caption[Network2]%
        {$\left(\begin{smallmatrix}1&0&1&0&1\\0&1&0&1&0\\1&0&-4&0&1\\0&1&0&1&0\\1&0&1&0&1\end{smallmatrix}\right)$}
        \label{fig:rand}
    \end{subfigure}
    \hfil
    \begin{subfigure}[t]{0.45\textwidth}
        \includegraphics[width=\textwidth,height=44mm]{figs/sharpen.eps}
        \caption[]%
        {{\small $\left(\begin{smallmatrix}0&-1&0\\-1&5&-1\\0&-1&0\end{smallmatrix}\right)$}}
        \label{fig:sharpen}
    \end{subfigure}
