I have tried this.Whether I use CHAIN_APPROX_NONE or CHAIN_APPROX_SIMPLE,in both case I get only 4 Adjacent Points.I have used the function as this: findContours(ContourImg, contours, // a vector of contours CV_RETR_EXTERNAL, // retrieve the external contours CV_CHAIN_APPROX_NONE); // all pixels of each contours Do I need to change any parameters to get all the points(or extreme points)? Is there anything wrong with this? or any other method to be used? |

Hello All, I am using Findcontour and drawcontour for contour Processing.The output array of findcontour function contains 4 adjacent points on Top Left corner of contour.I want All the points contained in contour,so I can retrieve specific points(Extreme Points)from it.Does anybody know,what is the method to achieve this? |
