mmdFlow
Detect water in a static image of an oil-water flow experiment.

The gray-scale image of the water-oil flow experiment is read.

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

a

The dark region of the image is enhanced by the close top-hat operator.

Image b = mmCloseth(a, mmSeline(50, 90));
mmShow(b);

b

A connected filtering is applied to remove small artifacts present in the image.

Image c = mmCloserec(b, mmSebox(5));
mmShow(c);

c

An alternated sequential filtering is used for shape smoothing.

Image d = mmAsf(c, "co", mmSecross());
mmShow(d);

d

The original and thresholded image overlayed on the original are presented successively.

Image e = mmThreshad(d, 100);
mmShow(a);
mmShow(a, e);
