The gaussian filter we use comes from the \texttt{scipy.ndimage} module. We use

|
this function instead of our own function, because the standard functions are

|

-most likely more optimized then our own implementation, and speed is an important

\paragraph*{Larger amounts of dirt}

Larger amounts of dirt are not going to be resolved by using a Gaussian filter.

-We rely on one of the characteristics of the Local Binary Pattern, only looking at

|
|
|
-dirt, and the fact that the characters are very black, the shape of the characters
|
|
|
-will still be conserved in the LBP, even if there is dirt surrounding the character.
