MJ2 is a video category category format that contains the motion sequence of JPEG 2000 images. This video encoding system, which uses JPEG 2000 intraframe compression technology, was developed at the Fraunhofer Institute of Integrated Circuits (FIS). Since November 2001, it has existed as an international ISO / IEC standard. The codec is based on a discrete conversion. Compared to the MPEG family used in codecs, it performs encoding in two areas simultaneously. Both in spatial and in frequency. In this case, there is no need to split the images into blocks. Only intra-frame compression is used for each frame, and inter-frame coding is not applied. A distinctive feature of MJ2, that is, Motion JPEG 2000 Video Clip, is that it can be scaled. And not only in terms of frame size. And in quality, that is, in terms of video stream speed, too. The decomposition features are such that each frame can have its own copies, which are two times less vertically and horizontally. Since it is possible to compress without loss, it is possible to use this codec in the medical industry. After all, it is necessary for images to have high accuracy. Synchronization with video supports embedded audio.
PCX is one of the first bitmap image formats developed by ZSoft for the PC Paintbrush program. This is the original bitmap format for the DOS / Windows platform. It supports monochrome single-bit black and white images, an eight-bit gray scale, indexed color images, and full-color 24-bit RGB model images. But there is no support for additional color and alpha channels, clipping paths, color management. The format provides for the application of the simplest compression algorithm (RLE) so that information is not lost. Now it has a purely historical significance. The PCX file format has been replaced by newer image formats. However, the format is still used in separate applications in order to scan and send faxes. PCX multi-page fax documents use the .DCX extension. Most DOS-based programs are suitable for viewing PCX (PC eXchange) files. In particular, the viewer Norton Commander. The big drawback of the PCX format is that it has too many versions. This can be explained by the fact that the PCX standard is open, and therefore it has been widely used by most independent software developers. And therefore it is constantly updated.
