Perhaps the simpler solution in this case is to use \only
:
\documentclass{beamer}
\begin{document}
\begin{frame}
\begin{table}
\caption{Table}
\begin{tabular}{l c c c c c c}
\hline \hline
No. & {Ordinary} & {Blue} & {Pink} & {Yellow} & {Green} & {RCM}\\
\hline
\only<1>{
&\multicolumn{6}{c}{$\alpha$=0.05}\\
H=2 & 95.0 & 75.3 & 75.7 & 79.5 & 72.0 &\\
H=3 & 95.6 & 87.0 & 87.3 & 87.6 & 85.2 & \\
H=4 & 95.0 & 91.6 & 91.9 & 90.3 & 90.2 & 93.3\\
H=5 & 95.2 & 93.5 & 93.7 & 91.3 & 91.8 & 94.3\\
H=6 & 94.9 & 93.8 & 94.1 & 92.6 & 92.8 & 94.7 \\[-\normalbaselineskip]
}
\only<2>{
&\multicolumn{6}{c}{$\alpha$=0.5}\\
H=2 & 95.0 & 91.4 & 91.2 & 79.5 & 99.9 & \\
H=3 & 95.6 & 95.1 & 95.1 & 87.6 & 95.1 & \\
H=4 & 95.0 & 94.8 & 94.8 & 90.3 & 93.5 & 95.5 \\
H=5 & 95.2 & 95.1 & 95.2 & 91.3 & 93.1 & 95.9 \\
H=6 & 94.9 & 94.8 & 94.8 & 92.6 & 93.4 & 95.5 \\[-\normalbaselineskip]
}
\\\hline
\end{tabular}
\end{table}
\end{frame}
\end{document}

Or a simple variation showing each part separately and finally the whole table:
\documentclass{beamer}
\begin{document}
\begin{frame}
\begin{table}
\caption{Table}
\begin{tabular}{l c c c c c c}
\hline \hline
No. & {Ordinary} & {Blue} & {Pink} & {Yellow} & {Green} & {RCM}\\
\hline
\only<1,3>{
&\multicolumn{6}{c}{$\alpha$=0.05}\\
H=2 & 95.0 & 75.3 & 75.7 & 79.5 & 72.0 &\\
H=3 & 95.6 & 87.0 & 87.3 & 87.6 & 85.2 & \\
H=4 & 95.0 & 91.6 & 91.9 & 90.3 & 90.2 & 93.3\\
H=5 & 95.2 & 93.5 & 93.7 & 91.3 & 91.8 & 94.3\\
H=6 & 94.9 & 93.8 & 94.1 & 92.6 & 92.8 & 94.7 \\[-\normalbaselineskip]
}\only<3>{\\}
\only<2,3>{
&\multicolumn{6}{c}{$\alpha$=0.5}\\
H=2 & 95.0 & 91.4 & 91.2 & 79.5 & 99.9 & \\
H=3 & 95.6 & 95.1 & 95.1 & 87.6 & 95.1 & \\
H=4 & 95.0 & 94.8 & 94.8 & 90.3 & 93.5 & 95.5 \\
H=5 & 95.2 & 95.1 & 95.2 & 91.3 & 93.1 & 95.9 \\
H=6 & 94.9 & 94.8 & 94.8 & 92.6 & 93.4 & 95.5 \\[-\normalbaselineskip]
}
\\\hline
\end{tabular}
\end{table}
\end{frame}
\end{document}

Another possibility, producing a different kind of overlay, is to use \onslide
:
\documentclass{beamer}
\begin{document}
\begin{frame}
\begin{table}
\caption{Table}
\begin{tabular}{l c c c c c c}
\hline \hline
No. & {Ordinary} & {Blue} & {Pink} & {Yellow} & {Green} & {RCM}\\
\hline
\onslide<1->{
&\multicolumn{6}{c}{$\alpha$=0.05}\\
H=2 & 95.0 & 75.3 & 75.7 & 79.5 & 72.0 &\\
H=3 & 95.6 & 87.0 & 87.3 & 87.6 & 85.2 & \\
H=4 & 95.0 & 91.6 & 91.9 & 90.3 & 90.2 & 93.3\\
H=5 & 95.2 & 93.5 & 93.7 & 91.3 & 91.8 & 94.3\\
H=6 & 94.9 & 93.8 & 94.1 & 92.6 & 92.8 & 94.7 \\
}
\onslide<2>{
&\multicolumn{6}{c}{$\alpha$=0.5}\\
H=2 & 95.0 & 91.4 & 91.2 & 79.5 & 99.9 & \\
H=3 & 95.6 & 95.1 & 95.1 & 87.6 & 95.1 & \\
H=4 & 95.0 & 94.8 & 94.8 & 90.3 & 93.5 & 95.5 \\
H=5 & 95.2 & 95.1 & 95.2 & 91.3 & 93.1 & 95.9 \\
H=6 & 94.9 & 94.8 & 94.8 & 92.6 & 93.4 & 95.5 \\[-\normalbaselineskip]
}
\\\hline
\end{tabular}
\end{table}
\end{frame}
\end{document}

Here's a possibility using TikZ (an advantage is the easy integration with beamer overlay specification):
\documentclass{beamer}
\usepackage{tikz}
\begin{document}
\begin{frame}
\begin{tikzpicture}
\node[anchor=south west,inner sep=0] (image)
at (0,0)
{\includegraphics[width=\textwidth,height=6cm]{example-image-a}};
\begin{scope}[x={(image.south east)},y={(image.north west)}]
\node<2-> at (0.78,0.75) {%
\begin{tabular}{@{}ll@{}}
RMSE & 0.059m \\
NSE & 0.798
\end{tabular}%
};
\node<3-> at (0.78,0.20) {%
\begin{tabular}{@{}ll@{}}
RMSE & 0.042m \\
NSE & 0.298
\end{tabular}%
};
\end{scope}
\end{tikzpicture}
\end{frame}
\end{document}
![enter image description here](https://i.stack.imgur.com/hblRa.gif)
The other advantage of this approach is that the coordinates for placement are relative to the image: (0,0) represents the bottom left corner, and (1,1) is the top right corner. A grid can also easily be placed for additional visual help:
\documentclass{beamer}
\usepackage{tikz}
\newcommand\MyGrid{%
\draw[help lines,xstep=.1,ystep=.1] (0,0) grid (1,1);
\foreach \x in {0,1,...,9} { \node [anchor=north] at (\x/10,0) {0.\x}; }
\foreach \y in {0,1,...,9} { \node [anchor=east] at (0,\y/10) {0.\y}; }
}
\begin{document}
\begin{frame}
\begin{tikzpicture}
\node[anchor=south west,inner sep=0] (image)
at (0,0)
{\includegraphics[width=\textwidth,height=6cm]{example-image-a}};
\begin{scope}[x={(image.south east)},y={(image.north west)}]
\MyGrid
\end{scope}
\end{tikzpicture}
\end{frame}
\end{document}

This is an adaptation of the method described in Drawing on an image with TikZ.

Remarks
When including an image using
\includegraphics
from thegarphicx
package (preloaded by beamer), then you can specify the optionsclip
andtrim
, wheretrim
takes additional parameters for the borders. In conjunction withclip
the trimmed borders are cut off. When omittingclip
only the borders are shift (i.e. the bounding box changes).The
