Phase fraction calculation of microstructure

Phase fraction calculation for optical and SEM microstructure. Can do single and Batch processing too. Enjoy!

%% Phase fraction calculation from optical or SEM microstructure. %%

% Works on Matlab 2021a (Not checked with previous version ;hopefully it works)

It is based on Adaptive image threshold. {https://uk.mathworks.com/help/images/ref/adaptthresh.html}

The sensitivity is set to default 0.8. It could be changed manually in code if required.

There are two options available

****************************************************************

Option one : Analaysis of single Image

Use the script names single_image_analysis.

=>select the image

=>Crop the image and double click

=>Should give you the result.

**************************************************************************

Option Two : Batch Image processing

This is useful when you have several images to process at one go.

{https://uk.mathworks.com/help/images/batch-processing-using-the-image-batch-processor-app.html}

Open matlab => open apps=> select Image Batch Processer

=> load the folders with all the images

=> Under Function name, browse the batch_processing script file

=> Under Process you can select either single or all and run.

=> Crop the image and double click for all the image.

=> Enter the threshold sensitivity. Generally it varies from 0-1. Adjust according to your image quality.

=> you can see the results at right column for respective image

=> Under Export option => you can export result of all processed image to workspace.

=> Tick the required black ,white fraction and name of the image and export.

=> you should be able to see the allresults in workspace.

=> Use this to save as excel in cmd :

{writetable(allresults,'statistics.xls','WriteRowNames',true) }

It would be saved in matlab directory.

Hope you enjoy it !
