mango.image.discrete_gaussian_gradient_magnitude

mango.image.discrete_gaussian_gradient_magnitude(input, sigma=1.0, errtol=0.01)

Discrete-Gaussian gradient magnitude (equavalent to Discrete Gaussian blur followed by gradient magnitude).

Parameters:

• input (mango.Dds) – Image for gradient magnitude.
• sigma (float) – The Discrete-Gaussian standard deviation.
• errtol (float) – Error tolerance which determines the size of the kernel window.

Return type:

mango.Dds

Returns:

Gradient magnitude image.
