%% 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. {}
The sensitivity is set to default 0.5. 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.
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.
=> 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 !
