减少子浮动和子标题之间的间隙

Question

如何减少子浮动和其标题之间的间隙？我尝试使用

\captionsetup[subfigure]{aboveskip=0pt} 

但它对我不起作用。下面是我的代码片段和输出

\begin{figure}
\captionsetup[subfigure]{labelformat=empty}
\captionsetup[subfigure]{aboveskip=0pt}
    \centering
    \subfloat[Ground Truth]{{\includegraphics[width=\textwidth]{ood-ms/ood-1-gt.png} }}
    \\ \vspace{-1\baselineskip}
    \subfloat[Recurrent Neural Network]{{\includegraphics[width=\textwidth]{ood-ms/ood-1-rnn.png} }}
    \\ \vspace{-1\baselineskip}
    \subfloat[]{{\includegraphics[width=\textwidth]{ood-ms/ood-1-vrnn.png} }}
    \\ \vspace{-0.5\baselineskip} \noindent\rule{14cm}{0.4pt}
    \subfloat[]{{\includegraphics[width=\textwidth]{ood-ms/ood-3-gt.png} }}
    \\ \vspace{-1\baselineskip}
    \subfloat[]{{\includegraphics[width=\textwidth]{ood-ms/ood-3-rnn.png} }}
    \\ \vspace{-1\baselineskip}
    \subfloat[]{{\includegraphics[width=\textwidth]{ood-ms/ood-3-vrnn.png} }}
    \\ \vspace{-0.5\baselineskip} \noindent\rule{14cm}{0.4pt}
        \subfloat[]{{\includegraphics[width=\textwidth]{ood-ms/ood-1-gt.png} }}
    \\ \vspace{-1\baselineskip}
    \subfloat[]{{\includegraphics[width=\textwidth]{ood-ms/ood-1-rnn.png} }}
    \\ \vspace{-1\baselineskip}
    \subfloat[]{{\includegraphics[width=\textwidth]{ood-ms/ood-1-vrnn.png} }}
    \\ \vspace{-0.5\baselineskip} \noindent\rule{14cm}{0.4pt}
    \subfloat[]{{\includegraphics[width=\textwidth]{ood-ms/ood-3-gt.png} }}
    \\ \vspace{-1\baselineskip}
    \subfloat[]{{\includegraphics[width=\textwidth]{ood-ms/ood-3-rnn.png} }}
    \\ \vspace{-1\baselineskip}
    \subfloat[]{{\includegraphics[width=\textwidth]{ood-ms/ood-3-vrnn.png} }}
    \\ \vspace{-1\baselineskip}
    \caption{}
    \label{fig:ms}
\end{figure}

像这样？

我宁愿使用来自包的\subfloat环境而不是来自包的环境，并且对于规则使用来自包的：subfigtabular\midrulebooktabs

\documentclass{article}
\usepackage[demo]{graphicx}
\usepackage{caption}
\usepackage{booktabs}

%-------------------------------- show page layout, only for test
\usepackage{showframe}
\renewcommand\ShowFrameLinethickness{0.15pt}
\renewcommand*\ShowFrameColor{\color{red}}
%---------------------------------------------------------------%

\begin{figure}[p]
