 Figure~\ref{Figure2:InterPuPartitions} illustrates the possible \ac{cu} partitioning into \acs{pu}.
 %One should note that the partition type applied to the \ac{cu} is also applied to divide the \ac{cb} into \acs{pb}.
 Figure~\ref{Figure2:InterPuPartitions}~(a) shows the symmetric partitions.
-The $N \times N$ corresponds to the case where the \ac{cu} is not further divided.
-The \ac{hevc} standard defines the horizontal and vertical division into two \acs{pu}, corresponding to the $\frac{N}{2}\times N$ and $N \times \frac{N}{2}$ cases, respectively.
-Finally, the $\frac{N}{2} \times \frac{N}{2}$ case results in four \acs{pu}.
+The $2N \times 2N$ corresponds to the case where the \ac{cu} is not further divided.

+Finally, the $N \times N$ case results in four \acs{pu}.
 The partitions shown in Figure~\ref{Figure2:InterPuPartitions}~(b) correspond to the asymmetric partitioning, which is one of the main improvements introduced in \ac{hevc},  as it allows higher flexibility in motion estimation, leading to higher compression efficiency~\cite{HEVCBlock2012}.
 These partitions types are only allowed for \acs{cu} with $16\times16$ pixels or larger.
