mango.image.discrete_gaussian_gradient_kernel

mango.image.discrete_gaussian_gradient_kernel(axis=0, sigma=1.0, errtol=0.01, dim=3)

Discrete-Gaussian convolution kernel.

Parameters:

• sigma (float) – The Discrete-Gaussian standard deviation.
• errtol (float) – 1D Error tolerance which determines the size of the kernel window, smaller value gives larger kernel window.
• dim (int) – Spatial dimension of kernel.

Return type:

numpy.array

Returns:

A dim dimensional Discrete Gaussian kernel.
