mmopenrecth - Open-by-Reconstruction Top-Hat.

Input: f: Gray-scale (uint8 or uint16) or binary image (logical uint8).; bero: Structuring element. (erosion) Default: Elementary cross (mmsecross).; bc: Structuring element. ( connectivity) Default: Elementary cross (mmsecross).

Output: y: Gray-scale (uint8 or uint16) or binary image (logical uint8). (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)

Algorithm

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