mmdSoil
Detect fractures in soil.

The image of fractures in soil is read.

Image a = mmReadgray("soil.tif");
mmShow(a);

a

The fracture lines are enhanced by the close top-hat operator.

Image b = mmCloseth(a,mmSebox(2));
mmShow(b);

b

Small connected bright regions are removed by the gray-scale area open operator. Note the connectivity used (mmSebox : 8-connected).

Image c = mmAreaopen(b,80,mmSebox());
mmShow(c);

c

The fracture lines are detected. This threshold is very robust.

Image d = mmThreshad(c,15);
mmShow(d);

d

Overlay of the fracture lines over the original image.
