In this document an algorithm is proposed to identify the
state (available/occupied) of the parking spaces in outdoor
areas. The algorithm was developed based on two features:
the average local entropy, and the standard deviation of the
average entropies of subregions of each parking space. The
algorithm delivers a binary map, which contains the number
of each parking space with its attributes such as area,
position and label. The dispersion of the histogram (entropy)
is an important factor to extract the information from
the frames, since this allows to know if there is uniformity in
gray values when there are or there are not any parked vehicles
in the parking spaces. With the entropy, it is possible
to calculate the two main features posited in this project.
A Support Vector Machine (SVM) is proposed by using a
linear kernel in order to ensure detection of vehicles.
