How to calculate Grain size using using ImageJ | Quick & Easy Histogram 

This is one best way to get the actual size of the particle. I have tried automated method (analyse particle) but that gave weird results especially if your image is underexposed/differently exposed in some area and it also not recognize all the particles in the image. Despite you give cutoff value, the automated method sometimes reconsiders dart/artefacts that give false-positive results.

Absolutely great tutorial. It covers almost everything in as simple language as it is possible. This is going to go in my favorites.

You can automate getting the largest and smallest diameter by thresholding the image and using the Feret's Diameter measurement in Analyze function. I use it for measuring pore spaces.

is it necesary to measure both length and width of same particle ...

0:19 absolute legend line. never seen any youtube do that before.

This is not bad ..rather good idea.Thank you.

Super bad 😁 Why do people like bad things so much 😭 I realized why it's important. Is there anyone else loving this bad way, like me?

H, I think you are measuring both the length and width of grain at the same time. In the results, you are showing both as to length. This is not correct. This should be shown as both the length and width separately. You should separate data and calculate the values separately. You might be right that's how they measure length for grain analysis. Area measurement is fine. In the end, I have to say good effort. Is it possible to automate the measurement? If someone has lots of images to analyse how are they going to do it manually. How do you set the thresh hold? Thanks

Perfect! Thank you, very helpful

Its too random. What is the area and length of that particular grain? You have done the area and length separately. So in the origin table one row doesnt contain size of a single particle.

Please sir make a video on How to calculate PORE SIZE, PORE DIAMETER from SEM images using ImageJ software.. Please!

Very helpful but how to fit Gaussian distribution over this histogram

Depois da grande ajuda a melhor coisa desse vídeo é a música de fundo haha Obrigadaaaa!

Thank you for your guiding video. It's very useful for me.

thank you it was very helpful

Thanks so much for sharing its so impresive

Thank you for sharing :) Can I know the principal (sphere fitting ......or else ) that the software uses to calculate diameters especially if particles have an irregular shape note really spherical.

Thanks that's a good idea 🎉❤

Love the Music... rest i will see soon

The best way!! Thank you for instruction!

This is super amazing and helpful

Hi..Thanks for the Video, Threshold result is not giving accurately in my case. Can any one help me to fix this.?

great thank you so much sir🤗☺☺

Very nice ....video and narration

Great 👍 Thank you 😊

Is it according to the ASTM standard ?

imagej ka ye wala version download nh horaha m using windows 7 can anyone help me out ? its urgent

mean is particle size. Am I right?

But how to plot count vs grain size graph?

Very helpful video, thank you.

Sir, I have a question. What magnification is needed for finding grain size? Is 5000x enough?

Thanks for your tutorial!!

Is there any possibility of getting X coordinates for all the bars in a histogram plot that's in image format (JPEG).

superb hats off to you dear

Great! Tanks a billion💐💯

Thanks for the tutorial

very nice

Thanks bro it was verry helpful

Great video! Is it possible to calculate oscillating frequency of water droplet using ImageJ?

thats such an amazing tutorial

Nice one. Loved it

how many particle did you measure?

thank you

fantastic

this is awesome buddy ..

Informative tutorial

Thanks for sharing! ^_^

you can not compare length and area. it is not correct! you have to find diameter from area and then use.

Liked the music. Where can i find it?

good one

TYSM!

is area represents size ?

Good choice of song - what is it?

Good

NICE BRO

good

genius

I like it

i did not like it, waste of time, thousand of particles are there how can handle it?

Do it automatically with Matlab.

Good
