Modifying the application

Now that we have high-level functions and classes for several filters, it is trivial to apply any of them to the captured frames in Cameo. Let's edit cameo.py and add the lines that appear in bold face in the following excerpt:

import cv2
import filters
from managers import WindowManager, CaptureManager

class Cameo(object):
    
    def __init__(self):
        self._windowManager = WindowManager('Cameo',
                                            self.onKeypress)
        self._captureManager = CaptureManager(
            cv2.VideoCapture(0), self._windowManager, True)
        self._curveFilter = filters.BGRPortraCurveFilter()
    
    def run(self):
        """Run the main loop."""
        self._windowManager.createWindow()
        while self._windowManager.isWindowCreated:
            self._captureManager.enterFrame()
            frame = self._captureManager.frame


            
            filters.strokeEdges(frame, frame)
            self._curveFilter.apply...
