Claim One:
1. A method of extracting and reconstructing court lines in an image showing a court, comprising: executing a processor to binarize a court image of a court having court lines to form a binary image, the binary image reducing the court image in image content to visually isolate the court lines in the court image from other features in the court image; executing a processor to search for a plurality of corners in the binary image and defining a court line range based on the plurality of corners; executing a processor to apply a linear transformation to form a plurality of linear segments respectively extending between the corners within the court line range; executing a processor to define at least one first cluster and at least one second cluster according to predetermined characteristics of the linear segments, and categorizing the linear segments into a plurality of groups according to the first cluster and the second cluster; executing a processor to determine for each group a standard court line based on an averaging of the linear segments of the group, and generating a linear equation for each standard court line to locate respective positions of points of intersection of the standard court lines; and executing a processor to reconstruct the court image by superimposing thereon indicia representative of the standard court lines according to the points of intersection.
