Algorithm 1 Searching particle Algorithm 1.
1:	Definition of min and max value for subimages
2:	Image reading
3:	for each defined value in size of image do
4:	Obtain grey code of subimage
5:	Compute histogram of subimage
6:	Define threshold value
7:	Obtain black and white of subimage
8:	Search the particle
9:	while (detecting particle = 1) do
10:	Measure particle size
11:	Find location
12:	Label particle
13:	end while
14:	end for
