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 
        shortcomings?  
   * 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 
     and hardware?  
   * 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.
