Proposes a variable filter, a new high-resolution Hough transform method. A voted value at the point (ρ,θ) on the Hough space is transformed into a value distribution by the variable filter, and voting is performed according to the distribution. The shape and size of the variable filter changes dynamically with the quantization size and the line parameters (ρ,θ). Statistical experiments show that the filter can improve extraction performance and reduce the mean error of extracted line parameters even with noisy images
