Hai All,
I have a lot of SEM and TEM images. I want to measure a particle size of my samples from the images. Could you or anyone to help me to do that with origin. FYI, I have OriginPro 8.6.
Because I am a new Origin user, could you please let me know the procedurs step by step.
Thank you very much in advance.

Hai All,
Sorry,I forgot.
I need to get not only the particle size but also their distribution and some graphs which are usually presented in report about particle size. |

Hi NZN,
Sorry, we do not have a way to identify, count, and quantify objects from an image currently in Origin.

Hi,
Aautomatic object identification is certainly a holy grail of image processing.
Until we get such marvel, if the objects are not many, and you are okay to
do manually, you can use both Digitizer tool in Origin, then run a little
script tool such as: //////////////////////////
nr=wks.maxRows;
nobj=0;
worksheet -a 1;
cpos=wks.nCols;
for(ii=1; ii<=nr; ii=ii+2) {
nobj++;
xx1=wcol(1)[ii];
xx2=wcol(1)[ii+1];
yy1=wcol(2)[ii];
yy2=wcol(2)[ii+1];
rr=Distance(xx1,yy1,xx2,yy2);
wcol(cpos)[nobj]=rr;
};
sum(wcol(cpos));
wcol(cpos)[L]$ = "Size";
wcol(cpos)[C]$ = "Count: $(sum.n)"+" Ave:$(sum.mean, %7.4f)";
////////////////////////which makes the list of sized like in the screenshot:

Hi nzn,
may be you can live with the way from Hideo but imho I would suggest to better use a software which is specialized in picture processing. I recommend ImageJ http://rsbweb.nih.gov/ij/. It is a well known Java based software which you can use for free. There is also a plugin available to measure, count and identify particles in pictures.
Best regards,
Steffen |

| It's not easy to do this in origin,even impossible. Our lab bought a new leica microscope, with a software siute, which has this function,based on the colour difference. if you need, you can send the image to me, maybe i can have a try on it. |

Hi,
I ask this question again since it's been 4 years now. Is there a way to measure the size and distribution of particles in SEM images with OriginPro 2015?
Like with the Image processing, spacial filter, edge tool?
Thanks,
Violette

Hi all,
I'm a new user of Origin and have a task to measure particle size/ Could anyone suggest how to measure nanoparticle size from the SEM image in OriginPro 9.1 or other software? Haven't found this possibility yet.
Would be very appreciate to any helpful answer.
Thanks in advance,
Katerina
