摘要：Provided is a line segment extraction device capable of accurately and rapidlyextracting a line segment. A pattern generating means relates an original image to cellsof a cellular automaton to generate time-series configuration patterns. A primarydetection means detects the movement of a cell in an active state and sets a primary flag

according to the configuration patterns generated in time series. This generates time-series primary flag patterns. A secondary detection means detects a cell in which thedirection of the primary flag and the direction of the movement thereof are matched toset a secondary flag according to the primary flag patterns generated in time series. Aline segment detection means records a line segment marker on a cell in which thesecondary flag in the opposite direction is generated, together with the direction. In thisway, the line segment is extracted.
