A method of recognizing linear pattern contained in the video data stored in an original video memory. A memory region of the original video memory is divided into a plurality of regions, projective waveforms at a plurality of different projection angles are found out for each of the regions from the video data of the divisions, the projection waveforms are analyzed to determine the presence or absence of any linear pattern, direction ( theta ) of line, line width (W) and line length (L) in each of the divisions, and a line segment corresponding to the linear pattern is picked up for each of the divisions based upon the results of determination. |
