dilate5x5

rlemasklib.RLEMask.dilate5x5(inplace=False)

Dilate a mask with a round 5x5 kernel.

The kernel is 0 in the four corners, otherwise 1:

Kernel:

At the image border, pixels are treated as if the mask was extended by replicating the edge values. This means dilation does not extend beyond the image boundary.

Parameters:

inplace (bool) – whether to perform the operation in place or to return a new object

Returns:

The RLEMask object representing the dilated mask (self if inplace=True)

Return type:

RLEMask

Examples

A single pixel dilates into the kernel shape:

.dilate5x5() ==
