Closed form line-segment extraction using the Hough transform

作者:

Highlights:

• We proposed a method for obtaining the complete set of line-segment parameters.

• The direction, length and width of a line-segment are extracted simul- taneously in a closed form.

• We provided a complete theoretical derivation of voting variance with respect to voting angle.

• The midpoint of a line-segment is determined by the coefficients of the fitted linear curve.

• Parallel, crossing, and aligned line-segments are discussed by analysing events in image space and Hough space.
