Multimedia: JPEG solid compression using a dedicated model

[Gonzalo Muñoz]

Fairytale will eventually support the lossless re-compression of jpg images using one of two methods. See issue #12 and #13. Nevertheless, both libraries are only capable of processing just one image at the time.

In the real world, though, we can often encounter very similar images on the same folder / data set. For example, a few camera shots on the same spot or screen-shots of the same program inside a help file. These similarities can be exploited to generate a much denser archive but only after undoing the compression of each individual file and recognizing them as valid images. Currently, we don't have the ability to do that but a good place to start is uncmpJPG by Matthias Stirner.
