Parameters
-----------
image : two-dimensional array
image : 2D array
Greyscale input image to detect edges on; can be of any dtype.
sigma : float
Standard deviation of the Gaussian filter.
low_threshold : float
Lower bound for hysteresis thresholding (linking edges).
If None, low_threshold is set to 10%.
If None, low_threshold is set to 10% of dtype's max.
high_threshold : float
Upper bound for hysteresis thresholding (linking edges).
If None, high_threshold is set to 20%.
If None, high_threshold is set to 20% of dtype's max.
mask : array, dtype=bool, optional
Mask to limit the application of Canny to a certain area.
Returns
-------
output : array (image)
output : 2D array (image)
The binary edge map.
