|Description||🔵 JPEG – is a popular graphic file format, which is characterized by a high degree of compression, which leads to a decrease in image quality. It uses the technology of encoding smooth color renditions, providing the ability to reduce the amount of data frequently during the image recording. Because of the small size, it is requested by the owners of websites, allowing you to save the traffic effectively. It is also frequently used in memory cards of digital video cameras. The JPEG algorithm is optimally suitable for compressing photographs and pictures in which realistic scenes with little contrast of colors are present. It is not recommended to use this format to compress drawings and various graphics since a big difference between several near located pixels provokes visible artifacts.|
|Technical details||🔵 The procedure for compressing the digital images in JPEG format is carried out in several stages. First, the photo is transformed into a color space YCbCr. Then it is divided into squares to determine the upper range of the color spectrum. Finally, the colors and brightness are coded. JPEG uses a "lossy" compression system and discrete cosine transform technology. The format acts simultaneously as the standard of ISO and the International Telecommunication Union. The file compression ratio is in the range from 10:1 to 100:1. In this case, the reduction in image quality can vary from insignificant to substantial.|

|Technical details||🔵 In 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.|
