Introduction
}
Licence plates are used all over the world. The plates are, usually, attached to the front and rear
of a motorised vehicle and used for indentifying this vehicle. Every
country can have more or less its own version of a licence plate, but all these systems do not
differ greatly. We will be focusing on the dutch system for licence plates.
\section
{
Problem Description
}
License plates are used for indentification and thus made to recognize from great
distances and still be seen in many weather conditions. Our learning set of photos contains
''' ik weet niet precies wat voor camera ''. The angle in which these pictures are taken or the angle
of the approaching vehicles are always different and some licence plates are a bit dirty,
but for a human they are still pretty easy to indentify. A computer or perhaps a small
chipset will need to be thourougly practiced. In short our program must be able to
do the following:
\begin{itemize}
\item
Find the location of the license plate.
\item
Use transformations so it gets an upfront view.
\item
Reduce noise where possible.
\item
Get the locations of each letter and extracting it.
\item
Apply a local binary pattern algorithm on each letter.
\item
Matching the found patterns with found results and return the best match.
\end{itemize}
\section
{
Solution
}
Now that we know the problem we can start with stating our solution. This will
come in a few steps aswell.
\subsection
{
Localizing the plate
}
The photos are of very high contrast. Most of the time only the lights of a vehicle
are visible in addition to the license plate. We can first crop the image untill
it finds brighter pixel values in a row or column. Then we can apply ''?? weet niet hoor'' local histogram
matching to find out whether we have a light or license plate.
\subsection
{
Transformations
}
Affine transformations will do the trick
\subsection
{
Reducing noise
}
Weet niet precies hoe, maar van die kleine rondjes / vlekjes / stipjes moeten
we wel een beetje weghalen want die maken het wel een beetje lelijk
\subsection
{
Extracting a letter
}
De karakteristiek bepalen van het dash/streepje (-) dan heb je in elk geval al
drie groepen met maar 1 of 2 letters (ws 2). Hier kun je volgens mij dan wel
makkelijk zoeken op een overgang van letter naar andere letter omdat er stuk
white-space tussenzit
\subsection
{
Local binary patterns
}
Hier moet een vrij groot verhaal omdat dit ons belangrijkste algoritme moet zijn
+ not sure if it will work out :o
\subsection
{
Matching the database
}
Als we al die histogrammen opslaan, hoe gaan we dat slim met elkaar vergelijken
(of naja sneller dan brute force)
\section
{
Conclusion
}
This will be fun.
