Class OrientedPolygonExtractionProcessor

java.lang.Object

org.openimaj.image.processing.extraction.OrientedPolygonExtractionProcessor

All Implemented Interfaces:

ImageProcessor<FImage>, Processor<FImage>

public class OrientedPolygonExtractionProcessor
extends Object
implements ImageProcessor<FImage>

Extract a polygon from an image into a new image. The ellipse fitting the polygon is extracted. The rotation of the ellipse is used to orientate the polygon. The major and minor axis of the ellipse form the dimensions of the output FImage The ProjectionProcessor is used to perform the extraction. Concretely, the projection processor is set up with a transform matrix combining the rotation of the ellipse and a translation using the COG of the ellipse.
