an x-ray fluoroscopy image of a heart with a catheter in the coronary vessel
indicated by the blue arrow. The apex (bottom tip) of the heart is indicated by

a. Use thresholding and edge detection techniques to find the outlines of the
heart.
b. Choose some seed values in the middle of the heart to start the region growing process to outline the heart.
c. Apply Canny edge detection technique to find the outlines of the catheter.
d. Apply Canny edge detection techniques to find the outlines of the ribs.
