摘要： A method of recognizing an arcuate or circular arc segment is used with an image processing apparatus. In a first step, two arbitray image structuring points are selected as segmenting end points from the dot-line image data. next, an image structuring point among the image structuring points present within a segment divided by the segment end points that is located furthest from and in a direction perpendicular to a straight line connecting the given structuring points and within a distance which is equal to or larger than a constant distance is extracted. The, three consecutive, adjacent polygonal-line structuring points are recognized as an arcuate or circular arc segment when a distance between a virtual circle passing through the three adjacent points and a median point of two line segments formed by the three consecutive points is equal to or less than the constant distance.

摘要： A linear image is traced on the basis of an instruction to trace the linear image through an image processing system for processing a trace of the linear image of data of an image, having an image memory for storing the data of the image, a data memory for storing data of a graphic, a display unit for displaying the data of the image and the data of the graphic, an input unit for entering the instruction, and a semi-automatic image trace processing section for processing the trace of the linear image on the basis of the instruction. The candidate of the branched direction is detected by tracing the linear image having a line width smaller than a predetermined line width; setting a point on a contour line of the linear image as a first trace base point when the trace detects a branched point at which the line width of the linear image to be traced expands temporarily; transferring the first trace base point on the contour line by a predetermined distance and setting a point existing on the contour line opposite to the contour line on which the first trace base point is located and in the position closest to the first trace base point, as a second trace base point; and detecting a middle point between the first trace base point and the second trace base point as a candidate of the branched direction.

摘要： A pattern recognition apparatus is capable of subjecting a large image region to image processing with an image memory having a small memory capacity and providing a contouring line data of an image in the same manner as processing with an image memory having a large memory capacity. The pattern recognition apparatus is provided with an image input means for inputting an image; an image data storing means for storing image data; a contouring line data storing means for storing contouring line data; and a contouring line data connecting means. The contouring line data connecting means is to partition image data into adjacent partitioned regions so as to allow them to overlap with each other by only one pixel, to delete a contouring line data in an overlapping portion of the adjacent partitioned regions from a contouring line data for the image data in each of the partitioned regions on the basis of a vector data passing in a predetermined direction, and to connect the contouring line data of an open drawing so as to match their terminal points in the overlapping portion thereof with each other, thereby providing a total contouring line data.

摘要： A method for re-tracing an end point of an image by an image processing device for converting the line images of the image data into vector data in a semi-automatic way by tracing plural line images and converting them into one vector data. The method for re-tracing the end point of the image involves tracing the line images by transferring the tracing points on the line images and continuing the previous trace processing for re-tracing the line image which follows by waiting for an instruction to re-trace from the input unit and entering the instruction to re-trace the image specified for re-tracing when the tracing point has reached the end point of the line image whose tracing points have been traced.
