Overwrite an image with new 'imfinfo' data.

General question:

Using 'imfinfo', can the generated structure be modified? Then can this modified structure be saved as an image file?

Context:

I have 2 sets of photos from drone surveys, standard images with GPS data and InfraRed images without. I want to copy the GPS data from the standard images and transfer it to the IR images.

Photogrammetry works with GPS images, and I'd like to create IR 3D models in the same capacity as the standard model from standard images, so I'd need to transfer the GPS coordinates from the standard images to the IR.

No, it cannot.

However, there is a File Exchange tool to write EXIF to JPEG; https://www.mathworks.com/matlabcentral/answers/152559-writing-exif-data-to-jpg

TIFF images can have their tags copied.

For PNG, see https://www.mathworks.com/matlabcentral/answers/303156-how-to-convert-dicom-image-to-jpeg-png-with-out-loosing-it-s-metadata#answer_235033

DICOM images can have their attributes copied.
