Abstract:
1. A method of estimating overlap between polygons, comprising: providing a pattern of objects over an entire area of a first polygon; determining a first amount of the objects that are located within the area of the first polygon; determining a second amount of the objects that are located within both the area of the first polygon and an area of a second polygon, the first polygon being a bounding area for content and the second polygon being a bounding area for a selection lasso, or the first polygon being a bounding area for a selection lasso and the second polygon being a bounding area for content; wherein the bounding area for content and the bounding area for the selection lasso are displayed on a display device; determining a ratio of the amount of objects that have been determined by a processor to be within the area of the first polygon to the amount of objects located within both the area of the first polygon and the area of the second polygon; estimating an overlap of the first polygon with the second polygon based on the determined ratio; determining a dimension of the first polygon; and providing one or more parallel lines spaced along the dimension of the first polygon, such that the lines intersect the polygon; and for each line,
