Algorithm
\end_layout
\begin_layout Itemize
find the closest index in the image data from the seed
\end_layout
\begin_deeper
\begin_layout Standard
closest_index=floor(seed +.5 ) then you can access QA & IND
\end_layout
\end_deeper
\begin_layout Itemize
do for all QA peaks
\end_layout
\begin_deeper
\begin_layout Itemize
check against QA threshold and if higher then return initial_direction from
IND[closest_index]
\end_layout
\begin_layout Itemize
While delta is True
\end_layout
\begin_deeper
\begin_layout Itemize
calculate the weights from the neighbors
\end_layout
\begin_layout Itemize
fow all 8 neighbors(weights)
\end_layout
\begin_deeper
\begin_layout Itemize
calculate new directions saved in direction
\end_layout
\begin_layout Itemize
new_direction += w[i]*directions
\end_layout
