Many formats of image files like jpg, png, tiff enable to read/write inside binary file information some comments, captions (so called IPTC data), EXIF data. They can accesible, for example, by XnView viewer, by Edit\Metadata\Edit IPTC data\ or by <Ctrl i> key combination.
It would be very useful and convenient to read/write such fields from Matlab to keep there some service information deals with image processing or parameters of image acquisiton.
Searching of Matlab answers and file exchange shows only possibility to read EXIF data or putting comments, annotation directly into image of such image file.
Is it possible and how is it possible to operate with such fields from Matlab?
Thank you
