我是 Latex 的新用户。最近我决定使用 latex 来准备我的项目，而不是使用 MS word。有谁能帮我为我的项目画出这个框图吗？
提前致谢，我非常感谢您的帮助。

与@Jojo 的答案非常相似，但是带有扭曲的箭头，\tikzset而不是\tikzstyle更短的代码（但有更多的库；-）。
\documentclass[tikz,border=3.14mm]{standalone}
\usetikzlibrary{positioning,decorations.markings,shapes.symbols,calc,backgrounds,shadows}
\begin{document}
\tikzset{twisted arrow/.style={decorate,decoration={markings,%
mark=at position 0 with {\coordinate (ta-base) at (0,0);},
mark=at position 0.5 with {\coordinate (ta-mid) at (0,0);
\pgftransformreset
\fill[#1!70!black] let \p1=($(ta-mid)-(ta-base)$) in
\pgfextra{\pgfmathsetmacro{\myangle}{ifthenelse(\x1>0,180,0)}}
([xshift=-2pt]ta-base) to[out=90,in=\myangle] (ta-mid)
to[out=\myangle,in=90] ([xshift=2pt]ta-base)
-- cycle;},
mark=at position 0.99 with {\coordinate (ta-end) at (0,0);
\pgftransformreset
\fill[#1] let \p1=($(ta-end)-(ta-mid)$) in
\pgfextra{\pgfmathsetmacro{\myangle}{ifthenelse(\x1<0,180,0)}}
(ta-mid) to[out=\myangle,in=90] ([xshift=-2pt,yshift=4pt]ta-end)
-- ++(-2pt,0) -- (ta-end) -- ++(4pt,4pt) -- ++(-2pt,0) to[out=90,in=\myangle]
cycle;
}
}},
dblock/.style={rounded corners,very thick,draw,white,fill=red,align=center},
flag/.style={draw,white,fill=blue!20,shape=signal}}
\begin{tikzpicture}[every shadow/.style={shadow xshift=0,shadow yshift=-0.5ex}]
\node[dblock,alias=r-0] (l-0) {The frame to be\\ displayed with\\ the
detection\\ overlaid};
\foreach \X [evaluate=\X as \Y using int(\X-1)]in {1,...,7}
{\node[dblock,right=1pt of r-\Y] (r-\X) {Frame\\ (i+\X)};
\draw[twisted arrow=red] (r-\Y.70) to[out=90,in=90,looseness=2] (r-\X.110);
\node[dblock,left=1pt of l-\Y] (l-\X) {Frame\\ (i-\X)};
\draw[twisted arrow=red] (l-\Y.110) to[out=90,in=90,looseness=2] (l-\X.70);}
\begin{scope}[on background layer]
\fill[red!20] ([yshift=-2pt]l-7.south west) -- ([yshift=-2pt]r-6.south east)
-- ++(0,-8pt) -- (r-7.east) -- ([yshift=10pt]r-6.north east) --
([yshift=2pt]r-6.north east) -- ([yshift=2pt]l-7.north west) -- cycle;
\end{scope}
\node[below=1cm of l-0,circle,fill=blue!20,align=center,text=white,draw=white, very
thick,font=\Large,drop shadow,alias=L-0] (R-0){TP\\ or\\ FP};
\begin{scope}[on background layer]
\foreach \X [evaluate=\X as \Y using int(\X-1)]in {1,...,7}
{\node[flag,right=0.5pt of R-\Y,signal from=west,signal to=east,minimum
width=1.5cm] (R-\X) {flag};
\node[flag,left=0.5pt of L-\Y,signal from=east,signal to=west,minimum
width=1.5cm] (L-\X) {flag};}
\end{scope}
\end{tikzpicture}

这是一些入门知识。我推荐这个软件包tikz。只需尝试一下位置、箭头和颜色。您可以单独创建节点，也可以循环创建节点。
\documentclass{standalone}
\usepackage{tikz}
\usepackage{xcolor}
\usetikzlibrary{calc, positioning, arrows}
