(a) Brown target in size $3\times3 m^2$. (b) Brown target in size $1\times1 m^2$ with one pixel ground truth location drift. (c - d) Faux Vineyard Green targets with potential sub-pixel nature, camouflage color and  tree canopy occlusion.}

\textcolor{myblue}{The contributions of this work are twofold. First, two sub pixel detectors, Sub-Pixel Adaptive Cosine Estimator (SPACE) and Sub-Pixel Spectral Matched Filter (SPSMF), were developed in this paper for sub-pixel hyperspectral target detection tasks under highly mixed and diverse background.}

结果

希腊字母加粗

注意： \mathbf不起作用 方案一、用\usepackage{amsmath} \boldsymbol{\sigma}

\mathbf 只对公式中的普通字母ABC…abcdef等起作用。

方案二、更好的方法是使用\usepackage{bm} \bm{}来加粗

公式编写

\mathbf{\Sigma}_{b}^{-1} \mathbf{s}}

结果

\begin{equation}
  \label{eq:ace}
  R_{\rm ACE}(\mathbf{s}, \mathbf{x})=\frac{\mathbf{s}^{T} \mathbf{\Sigma}_{b}^{-1} \mathbf{x}}{\sqrt{\mathbf{s}^{T} \mathbf{\Sigma}_{b}^{-1} \mathbf{s}} \sqrt{\mathbf{x} ^{T} \mathbf{\Sigma}_{b}^{-1} \mathbf{x} }},
\end{equation}

结果

 $\mathbf{\Sigma}_{b}$
