[mmgradm] [Up] [mmopenth] Residues

mmopenrecth
Open-by-Reconstruction Top-Hat.

Synopsis

function y = mmopenrecth ( f , bero , bc )

Input

f Image Gray-scale (uint8 or uint16) or binary image
bero Structuring Element

Default: 3x3 elementary cross

(erosion)
bc Structuring Element

Default: 3x3 elementary cross

( connectivity)

Output

y Image Gray-scale (uint8 or uint16) or binary image

(same type of f).

Description

mmopenrecth creates the image y by subtracting the open by reconstruction of f, defined by the structuring elements bero e bc, of f itself.

Examples

a = mmreadgray('keyb.tif');

mmshow(a);

b = mmopenrecth(a,mmsebox(4));

mmshow(b);
a b

Equation

Algorithm

function y=mmopenrecth_equ( f, bero, bc)
  y = mmsubm(f,mmopenrec(f, bero, bc));
