画一个带有两个箭头的图形

我想画出附图，但是我不知道如何添加两个箭头以及如何在箭头上标注名称。你能帮我吗？提前谢谢了。 图像

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{shapes,arrows.meta,decorations, positioning, arrows.meta, calc, shapes.geometric}
\begin{document}

\begin{tikzpicture}[block/.style={draw, fill=blue!15, rectangle, minimum height=1.7em, minimum width=2em},

blocksmallev/.style={draw, fill=blue!15, rectangle, minimum height=1.8cm, minimum width=1.2cm},
input/.style={coordinate},
arr/.style = {-Stealth},
\node [blockev, minimum height =2.5cm, minimum width=3.5cm, label={[above, very thick, font = \large]}](celll) at (-1.26,-2.74){} ;

\node[input, name = input, font = \normalsize] (input){};
\node[blockev, right = 0.4cm of input,  font = \normalsize] (feature) {\textbf{Feature} \textbf{extraction}};

\node[blocksmallev, left = 0.35cm of feature,  font = \normalsize] (segmen) {{\shortstack{\textbf{Segmentation}\\ \textbf{Module}}}};

\node[blocksmallev, fill = blue!50, right = 0.55cm of feature,  font = \normalsize] (class) {{\shortstack{\textbf{Classification }\\ \textbf{ Module}}}};

\node[blocksmallev, fill = blue!50, right = 0.55cm of class,  font = \normalsize] (recon) {{\shortstack{\textbf{Reconstruction }\\ \textbf{ of each}}}};
\node[blocksmallev, fill = blue!50, right = 0.55cm of recon,  font = \normalsize] (aggre) {{\shortstack{\textbf{Aggregation }\\ \textbf{ of each}}}};

作为起点，我给你一个提示，告诉你如何从一个节点画出这两个箭头。

来自一个节点的两个箭头

\documentclass[tikz,border=3.14mm]{standalone}

\usetikzlibrary{shapes,arrows.meta,decorations, positioning, arrows.meta, calc, shapes.geometric}
\begin{document}

    \begin{tikzpicture}[node distance=2cm,
                        block/.style={draw, fill=blue!15, rectangle, minimum height=1.7em, minimum width=2em},
                        blockev/.style={draw, fill=blue!15, rectangle, minimum height=1.8cm, minimum width=1.8cm},
                        blocksmallev/.style={draw, fill=blue!15, rectangle, minimum height=1.8cm, minimum width=2.5cm},
                        input/.style={coordinate},
                        arr/.style = {-Stealth},]
    
    
        \node[blocksmallev,text width=2.5cm,align=center] (segmen) {\textbf{Segmentation Module}};
        
        \node[blockev,right= of segmen] (feature) {\textbf{Feature extraction}};
        
        \def\shft{5}
        \draw [arr] ([yshift=\shft mm]segmen.east) -- ([yshift=\shft mm]feature.west) node[above,midway] {Patch-1};
        \draw [arr] ([yshift=-\shft mm]segmen.east) -- ([yshift=-\shft mm]feature.west) node[above,midway](patchn) {Patch-n};
        \node[above=-1mm of patchn]{\vdots};
        
    \end{tikzpicture}
\end{document}

我使用了你在代码中所做的，即使特征提取在草图中的两个框中。
您可以随意调整shft以腾出更多空间。

现在，您的整个设计还有一些工作要做，您可能需要对其进行更多的组织。您可以在 TeX-SE 上找到许多类似的设计，它们可能会给您带来启发。

编辑：如何连接两个区块

有两个块

这里你必须使用锚点。我必须定义另一种类型的块，命名为smallblock并将上面的块放置在右侧segmen.north east，同时将其附加到north west锚点。这样上面的线就对齐了。下面的也一样，但位于南边。

然后，为了画箭头（并严格水平绘制），我必须让它们从东侧的交叉口开始段以及水平位置特征1。这个点坐标写成(segmen.east|-feature1)。那么它指向特征1。

\documentclass[tikz,border=3.14mm]{standalone}

\usetikzlibrary{shapes,arrows.meta,decorations, positioning, arrows.meta, calc, shapes.geometric}
\begin{document}
    \begin{tikzpicture}[node distance=2cm,
                        block/.style={draw, fill=blue!15, rectangle, minimum height=1.7em, minimum width=2em},
                        smallblock/.style={draw, fill=olive!15, rectangle, minimum height=7.5mm, minimum width=2em},
                        blockev/.style={draw, fill=blue!15, rectangle, minimum height=1.8cm, minimum width=1.8cm},
                        blocksmallev/.style={draw, fill=blue!15, rectangle, minimum height=1.8cm, minimum width=2.5cm},
                        input/.style={coordinate},
                        arr/.style = {-Stealth},]
    
    
        \node[blocksmallev,text width=2.5cm,align=center] (segmen) {\textbf{Segmentation Module}};
        
        \node[smallblock,right= of segmen.north east,anchor=north west] (feature1) {\textbf{Feature extraction}};
        \node[smallblock,right= of segmen.south east,anchor=south west] (feature2) {\textbf{Feature extraction}};
        
        \def\shft{5}
        \draw [arr] (segmen.east|-feature1) -- (feature1) node[above,midway] {Patch-1};
        \draw [arr] (segmen.east|-feature2) -- (feature2) node[above,midway](patchn) {Patch-n};
        \node[above=-1mm of patchn]{\vdots};
        
    \end{tikzpicture}
