Introduced as a patent in 1962, the Hough transform has motivated
great interest as a potentially effective technique for real-time
pattern recognition, being applied to the most diverse situations
ranging from astronomy to biscuit quality control. Despite the
seeming simplicity of the technique, those who have tried to apply
it to more demanding problems soon realized that the approach entails
a series of not so straightforward problems, such as those caused by
the discrete nature of the image and parameter spaces, which have
motivated a series of investigations and publications. In fact, some
of the most interesting and fruitful works on Hough transform have
been characterized by an integrated approach considering the
relationships between the Hough transform and other related and
complementary areas and techniques such as discrete geometry;
projections; Radon, Fourier, and Gabor transforms; and matched
filtering, to name but a few.
After so many years of investigations on the Hough transform, a
number of questions remain to be answered, such as:
* Should the Hough transform be treated as a technique in
itself or only a special case of more general concepts?
* Have we fully understood and circumvented the Hough transform
* How does the Hough transform compare with alternative techniques?
* What are the most effective algorithms for real-time applications?
* How can the Hough transform be effectively implemented in software
* In brief: Has the Hough transform come of age?
Every relevant and original development which can help to answer
such questions is welcomed for appreciation for the Special
Issue of JRTI.
