Less edgy
Let's now try to spot just the outer shape of the grapefruits, the circles. You can do this by applying a more intense Gaussian filter to first make the image smoother. This can be achieved by specifying a bigger sigma in the canny function.
In this exercise, you'll experiment with sigma values of the canny() function.
grapefruit.The show_image has already been preloaded.
