Abstract
The invention provides a two-phase method for identifying sets of collinear points in data points, e.g., derived from an image. During a first phase, the 'angle-finding' phase, the angular orientation of the lines defined by the sets of points is estimated. During a second phase, the 'line-finding' phase, sets of collinear points aligned at that angle are identified. The invention has application, for example, in finding parallel and perpendicular point sets in an image.
