Path from edited contour points ofxcv

heya!
I’m using ofxCv, and am trying to draw polylines from the points extracted from vector<vectorcv::Point > points.

However, when I add polylines from the points, they join with the contour polylines. How can I have the new polylines from the contour finder and points, without the original traced contour line? I tried polylines.clear() and resizing it but I’m not sure I’m doing it the right way. Do I need to build a path from the polylines, so it does not join with the original contour lines?

I have this, but I want it to only show the polyline without the traced shape of the head & face.

void ofApp::update(){
cam.update();
if (cam.isFrameNew()){
contourFinder.setTargetColor(targetColor, trackHs ? TRACK_COLOR_HS : TRACK_COLOR_RGB);
contourFinder.setThreshold(threshold);
contourFinder.findContours(cam);

}
points.clear();
points.resize(contourFinder.size());
for (int i =0; i< contourFinder.size(); i++){
points[i] = contourFinder.getConvexHull(i);
}
}

polylines.clear();
polylines.resize(contourFinder.size());
for (int i =0; i< contourFinder.size(); i++){
polylines[i] = contourFinder.getPolyline(i);
}
}

}

//--------------------------------------------------------------
void ofApp::draw(){
//cam.draw(0,0);
gui.draw();
ofSetColor(255,100);
ofSetLineWidth(1);

for (int i=0; i< points.size(); i++){
for (int j =0; j<8; j++){
ofPolyline polyline = contourFinder.getPolyline(i);
polyline.curveTo(points[0][0].x, points[0][0].y); // These curves are Catmull-Rom splines
polyline.curveTo(points[0][0].x, points[0][0].y); // Necessary Duplicate for Control Point
polyline.curveTo(points[0][1].x, points[0][1].y);
polyline.curveTo(points[0][2].x, points[0][2].y);
polyline.curveTo(points[0][3].x, points[0][3].y);
polyline.curveTo(points[0][4].x, points[0][4].y);
polyline.curveTo(points[0][5].x, points[0][5].y);
polyline.curveTo(points[0][6].x, points[0][6].y);
polyline.curveTo(points[0][6].x, points[0][6].y);
polyline.draw();
}
}

}

Let me know, thank you so much!
