A set of image FileFormat~s well suited for natural images. Standard [JPEG] uses lossy compression (Discrete Cosine Transform and quantisation) to significantly reduce file size while maintaining an acceptable image quality. JBIG is a specialization of [JPEG] for bi-level images (ie black and white). JPEG2000 is a newer, better format using wavelet compression -- which is [Patent] encumbered, so you're unlikely to see it implemented in OpenSource software. |

The "Joint" in the name refers to the fact that the standard is a joint effort between [ISO] and [ITU-T]. Like many [ISO] standards, you have to pay to get a copy of it. |
