abstract = "We present a comprehensive study of two important subspace
clustering algorithms and their contribution to enhance results
for the difficult task of matching images of the same object using
different devices at different conditions. Our experiments were
performed on two distinct databases containing urban scenes which
were tested using state-of-the-art matching algorithms. Our start
point was the hypothesis that low discriminant local point
descriptors lead to misclassification, which can be reduced
employing clustering techniques as filters. A significantly
amelioration of the results obtained for the two tested databases
was achieved, which indicates that subspace clustering techniques
have much to contribute at this kind of application. Another point
is whether the occurrence of obstacles like trees and shadows are
responsible for misclassification of images.",
