How to make gTruth objects from pixelLabel​ImageDatas​tore?

Hellow all,

I 'm prepairing pixel-label data for a semantic segmentation.

I made png files (m*n uint8) as a pixelLabel data without using ImageLabelar app.

I semi-automatically made these files with an algolism including cutting off by threshold and watershed segmentation.

I was able to make a pixelLabelImageDatastore with the code below, but I want to modify the pixelLabel data now.

I want to use ImageLabelar app for the modification.

How can I make gTruth object from pixelLabelImageDatastore?

Or is there any substitution to modify the pixelLabelImageDatastore with ImageLabelar?

Any help will be appreciated.

location='C:\Users\000000\OneDrive\AI\Image2019\pixelLabelPH';
classNames='bone';
pixelLabelIDs=1;
pxds = pixelLabelDatastore(location,classNames,pixelLabelIDs);

location2='C:\Users\000000\OneDrive\AI\Image2019\PH';
imds = imageDatastore(location2);

pximds = pixelLabelImageDatastore(imds,pxds);
