One canadjust the parameters of the morphological examples ,use custom kernel function : IplConvKernel * cvCreateStructuringElementEx ( int cols ,UGG Sale UK,int rows ,int anchor_x ,int anchor_y ,int shape ,int * value = NULL ) ;function parameters cols ,rows identifies the structure size of the rectangle .
Anchor_x ,Cheap Coach Bags,anchor_y identified a closed rectangular inner reference point of the horizontal and vertical coordinates .Shape is a custom kernel shape ,Nike Air Max,specific for the 1.CV_SHAPE_RECT core is rectangular 2.
CV_SHAPE_CROSS core is cross shaped spoon 3.CV_SHAPE_ELLIPSE nucleus is oval 4.CV_SHAPE_CUSTOM nuclear is user defined its release function for void cvReleaseStructuringElement ( IplConvKernel * element ) ;examples of code as follows :# include < ;cv.
