2014-03-15 18:03:29 -0600 | asked a question | Circular kernel with sectors as subregions opencv I am an opencv newbie . I need to create a circular kernel with 8 sectors as subregions to perform kuwahara filter on an image . I am creating the kernel using opencv as "Mat kernel=getStructuringElement(CV_SHAPE_ELLIPSE,Size(3,3),Point(-1,-1));" I need to obtain the sectors and subsequently apply the filter to it. Any ideas on how to get the sectors will be greatly appreciated . |
