Hello!
In order to use the images I have labeled on the matlab image labeler app for other tasks, I am needing to get jpeg images and json annotation files from the gTruth.mat and PixelLabelData files. How do I go about doing this?
Thank you!

Hi,
As per my understanding, you want to export .json file of gTruth from image labeler . You can refer to the link below to convert the generated .mat file to .json file:
