chosen.content: Yes! Here is Python code that performs a Canny edge detection with a slider:
  
  import cv2
  import numpy as np
  
  def canny_edge_detection(image):
      # Create a window to display the output
      cv2.namedWindow('Canny Edge Detection')
      
      # Create trackbar to adjust the resolution (thresholds) of the detected edges
      def on_threshold_change(value):
          # Apply Canny edge detection with the updated thresholds
          edges = cv2.Canny(image, value, value * 3)
          
          # Display the edges in the window
          cv2.imshow('Canny Edge Detection', edges)
      
      # Initialize the trackbar position
      initial_threshold = 100
      
      # Create the trackbar
      cv2.createTrackbar('Threshold', 'Canny Edge Detection', initial_threshold, 255, on_threshold_change)
      
      # Call the on_threshold_change function initially to display the edges
      on_threshold_change(initial_threshold)
      
      # Wait for a key press to exit
      cv2.waitKey(0)
      
      # Destroy all windows
      cv2.destroyAllWindows()
