DescriptionAT&T and functions first created DjVU as the technology used for compressing images and has a free and available source code, and it proxy to PDF. It allows the distribution of scanned documents, photographs, and high definition images on the internet. There are an entire set of DjVU viewers, browser add-ons, and devices to execute binary codes that exist on both Windows and Mac devices.
Technical detailsIn early 1990s and 2000s, AT&T developed DjVU by Yann LeCun, Leon Bottou, Patrick Haffner, and Paul G. Howard. It is viewed as superior compared to PDF due to its ability to convert large amounts of text to DjVU easily, its small-sized files, and people can use it freely. The separation of DjVU is categorized into three types of images: background, foreground, and mask image, whose resolution is higher. The compression algorithm IW44 is used for compressing foreground and background images, whereas the JB2 is using in compressing mask images. This leads to a significant reduction of an image.
