Abstract
The theoretical symmetry in Hough transform (HT) butterflies is addressed. The reason the symmetry is damaged in real HT butterflies is analysed and employed to propose a high accuracy HT. Experiment demonstrates that the proposed method obtains high accuracy straight line parameters without the exact position of the HT peak.
