abstract = "Oriented feature detectors are fundamental tools in image
understanding, as many images display relevant information in the
form of oriented features. Several oriented feature detectors have
been developed; some of the important families of oriented feature
detectors are steerable filters and Gabor filters. In this work, a
performance analysis is presented of the following oriented
feature detectors: the Gaussian second-derivative steerable
filter, the quadrature-pair Gaussian second-derivative steerable
filter, the real Gabor filter, the complex Gabor filter, and a
line operator that has been shown to outperform the Gaussian
second-derivative steerable filter in the detection of linear
structures in mammograms. The detectors are assessed in terms of
their capability to detect the presence of oriented features, as
well as their accuracy in the estimation of the angle of the
oriented features present in the image. It is shown that the Gabor
filters yield the best detection performance and angular accuracy,
whereas the steerable filters have the best performance in terms
of computational speed.",
