mmvdome - Remove domes with volume smaller than v.

Synopsis: y = mmvdome( f, v, Bc )

Input: f: Gray-scale (uint8 or uint16) image.; v: Volume parameter. Default: 1.; Bc: Structuring element. Structuring element (connectivity). Default: Elementary cross (mmsecross).

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

Description: mmvdome This operator removes connected domes with volume smaller than v. This function is very similar to mmvdome, but instead of using a grayscale criteria (contrast) for the dome, it uses a volume criteria.

Examples

Numerical example:

a = uint8([...
    4    3    6   1    3   5    2;...
    2    9    6   1    6   7   3;...
    8    9    3   2    4   9   4;...
    3    1    2   1    2   4   2]);
b = mmvdome(a,10,mmsebox)

b =
     4     3     6     1     3     5     2
     2     6     6     1     5     5     3
     6     6     3     2     4     5     4
     3     1     2     1     2     4     2

Signal example:

f = mmreadgray('r4x2_256.tif');
s=f(10,1:end/2);
t = mmvdome(s,20);
plot(s);
plot([s',t']);

Image example:

f = mmreadgray('astablet.tif');
mmshow(f);
fb = mmvdome(f,80000);
mmshow(fb);
mmshow(mmregmax(fb));
