More Information
Summary:A method for removing extraneous information from a drawing of a device having one or more parts, the extraneous information including a lead line and a part number, the method including detecting a starting point of a lead line with respect to a bounding box of the part number and determining a general direction of the starting point with respect to the bounding box, wherein the starting point is set as a current point; performing linear regression analysis of dark pixels in an area covered by a mask centrally located at the current point to yield a linear regression line slope; determining a next point based on the slope and the general direction; and updating the current point with the next point and repeating the performing and determining steps until the lead line ends; and removing the lead line based on a path traced by the starting and current points.
