grains.gala_light.imextendedmin

grains.gala_light.imextendedmin(image, h, connectivity=1)

Extended-minima transform. The extended minima transform is the regional minima of the h-minima transform. The implementation follows the MATLAB function under the same name.

Parameters

• image (ndarray) – The input array on which to perform imextendedmin.

• h (float) – Any local minima shallower than this will be flattened.

• connectivity (int, optional) – Determines which elements are considered as neighbors of the central element. Elements up to a squared distance of connectivity from the center are considered neighbors. If connectivity=1, no diagonal elements are neighbors.

Returns

bool ndarray – True at places of the extended minima.
