JPEG2000 offers a new coding of images with a hierarchical data
structure from which a user can pick up the only necessary codestream
for the generation of representation matched to his needs. Therefore, a unitary and multipurpose image exchange system can be made from
combining the new JPEG2000 technology and classical mailer tools.
This paper proposes such a flexible access method. The proposed server consists of two POP3 servers, a SMTP server, the image list database and the image database. The POP3 server performs user
authentication and provides the image list. The SMTP server receives the client's request and transmits the appropriate image.
First the user connects to the 1st POP3 server with ID and password, then receives the available image list as e-mails. One mail is sent for each available representation of an image, i.e. each JPEG2000 progression order and image format. The hash value of the codestream and the JPEG2000 progression order values are included in the Message-ID of each mail header. Information, such as the name of the image, size, quality of image, is written in the text. Then, the user orders an image by replying to the corresponding mail of the list. When the SMTP server receives the client's e-mail, it prepares the desired image, and provides a mail with that image to the client via the second POP3 server. The proposed system is validated with different platform mailer tools.
