Okay some keypoints
vector<Point>. On top of that you can call the convexHull function to find a surrounding contour of the keypoints.boundingRect or minAreaRect to get a upright or rotated bounding rectangle.Respected Steven,
Thank you so much for your kind reply, Let me try.
Thanks
I have search Opencv manual on google but i can't understand any thing from there, so again ..... I have get the points from the image , so how can i cropping the face area using this points?? Code : ArrayList<point> landmarks = ret.getFaceLandmarks(); for (Point point : landmarks) { int pointX = (int) (point.x * resizeRatio); int pointY = (int) (point.y * resizeRatio); canvas.drawCircle(pointX, pointY, 2, mFaceLandmardkPaint); } I really appreciate, if you people help me out thanks ...
I guess you have to read again. If you have the points, put them into a vector and call the function boundingRect on that vector of points.
