JPEG stands for ‘Joint Photographic Experts Group. A JPEG is an image format that impressively reduces an images size; however it does that at the cost of removing a lot of information.’ A lot of the time, the lost information is barely noticeable. When you save an image on your computer, you can set the desired degree of compression; however this comes at the expense of image quality. The majority of the time you can get a 3:1 compression without noticing much when you save a JPEG. JPEGs use an 8×8 grid and they perform a discrete cosine transformation on every image.

JPEG 2000 is more recent and more intensive JPEG standard. The JPEG 2000 allows for a much higher compression rate in comparison to the original JPEG. It uses a wavelet transformation on the images, which uses more computer power. However, as systems are becoming faster at a rapid rate these days, this is much less of a problem now than when the first JPEG standard came out. Within a JPEG the size of the compressible area can vary, so on a positive note, no tiling pattern appears to be evident.

A JPS is a ‘stereoscopic JPEG’ file, and it is simply a stereoscopic image file format that has been based upon a JPEGs compression.
