Hough
Transform
• The Hough transform is a method for detecting
lines or curves specified by a parametric function.
• If the
parameters are p1, p2, … pn, then the Hough
procedure uses an n-dimensional accumulator array
in which it accumulates votes for the correct parameters
of the lines or curves found on the image.
