Who knows the history of JPEG?[edit]

There is not even the release year. (talk) 06:54, 30 April 2012 (UTC)

Pre-JPEG software was used several years before the standard was set. IG JAS developed transmitting systems for radar-images using jpeg-type data compression already ca 1986 for the Gripen fighter. (talk) 10:59, 28 January 2014 (UTC)

What's the CORRECT DCT equation used for JPEG[edit]

According to in the "The DCT Equation" section, the DCT equation (as well as the normalization constants that depend upon where in the block it is) are DIFFERENT than those here in the Wikipedia article. Is this just a different (but still equivalent) form to what's shown here? Or is one of these actually wrong (either the Wiki article, or the other article)?

Need a better Video to show the continuosly varying JPEG compression[edit]

A better video could be utilized to showcase the compression scale from Q=100 to Q=1. Below are few reasons for my point: 1. The video is black and white i.e. grey scale. JPEG's strength lies in capturing and rendering the colors of natural images, photos. — Preceding unsigned comment added by (talk) 08:36, 6 July 2014 (UTC)


Should this vulnerability be added to this article? As with many compressible file formats, the relatively small size of some JPEG files can hide the requirements to view or process some JPEG files. For example, the webpage has a link to a 618KB JPG file of a 10,000 x 10,000 pixel 24-bit image, which if a program converted to an uncompressed format would require at least 300MB of memory or file storage. • SbmeirowTalk • 08:08, 22 November 2014 (UTC)

If this topic isn't added to this article, should we create an article similar in concept to Zip bomb, E-mail bomb, Billion laughs articles. Possibly name the article "JPEG bomb"? • SbmeirowTalk • 08:16, 22 November 2014 (UTC)

Has anyone come across an article/blog on the internet that describes this vulnerability? • SbmeirowTalk • 08:19, 22 November 2014 (UTC)
