Description

morph_hatmorph_hatMorphHatmorph_hatMorphHatMorphHat computes the union of the regions that are removed by an openingopeningOpeningopeningOpeningOpening operation with the regions that are added by a closingclosingClosingclosingClosingClosing operation. Hence this is the union of the results of top_hattop_hatTopHattop_hatTopHatTopHat and bottom_hatbottom_hatBottomHatbottom_hatBottomHatBottomHat. The position of StructElementStructElementStructElementStructElementStructElementstructElement does not influence the result.

Structuring elements (StructElementStructElementStructElementStructElementStructElementstructElement) can be generated with operators such as gen_circlegen_circleGenCirclegen_circleGenCircleGenCircle, gen_rectangle1gen_rectangle1GenRectangle1gen_rectangle1GenRectangle1GenRectangle1, gen_rectangle2gen_rectangle2GenRectangle2gen_rectangle2GenRectangle2GenRectangle2, gen_ellipsegen_ellipseGenEllipsegen_ellipseGenEllipseGenEllipse, draw_regiondraw_regionDrawRegiondraw_regionDrawRegionDrawRegion, gen_region_polygongen_region_polygonGenRegionPolygongen_region_polygonGenRegionPolygonGenRegionPolygon, gen_region_pointsgen_region_pointsGenRegionPointsgen_region_pointsGenRegionPointsGenRegionPoints, etc.

Attention

The individual regions are processed separately.

Result

morph_hatmorph_hatMorphHatmorph_hatMorphHatMorphHat returns 2 (H_MSG_TRUE) if all parameters are correct. The behavior in case of empty or no input region can be set via:

Otherwise, an exception is raised.
