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

ImageJ tutorial, the terrible one!
Grain size distribution analysis using ImageJ - Check how bad is this idea?
In this video, I am showing how to get histogram of particle size distribution using ImageJ software.
Please don't forget to comment with your opinion on how bad is this idea!

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.

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

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.

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

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?

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

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

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

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

Very helpful but how to fit Gaussian distribution over this histogram

[irvingmarquez]

Thanks so much for sharing its so impresive

[monalishachutia]

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!

[ToanNguyen-]

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

[shopasi]

Is it according to the ASTM standard ?

[amigurumisdaroh]

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

[RafiArya-yq]

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

[ZeeshanAkhtarKhanYAHYA]

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

[maksymchylii]

The best way!! Thank you for instruction!

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