binary_erosion(image, selem=None, out=None)
This function returns the same result as greyscale erosion but performs faster for binary images.
Morphological erosion sets a pixel at (i,j)
to the minimum over all pixels in the neighborhood centered at (i,j)
. Erosion shrinks bright regions and enlarges dark regions.
Binary input image.
The neighborhood expressed as a 2-D array of 1's and 0's. If None, use a cross-shaped structuring element (connectivity=1).
The array to store the result of the morphology. If None is passed, a new array will be allocated.
The result of the morphological erosion taking values in [False, True]
.
Return fast binary morphological erosion of an image.
Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.
Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)
SVG is more flexible but power hungry; and does not scale well to 50 + nodes.
All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
