Is it possible to access the headers and packet information from the JPEG 2000 compressed format?

The JPEG 2000 COMPRESSION coding standard stores the compressed stream and stores data of packets, tiles and header information. Is it possible to access the information from the JPEG 2000 compressed file through imwrite or file read?

If you want to access information related to an image, you could use the imfinfo function. You can find more details in the following documentation page:

I do not think that you could use imwrite. You could possibly use fopen and fread, and this will get you a stream of bytes for the image. Then you can use the JPEG standard to find the specific headers you are looking for.
