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.
J2C is an advanced version of the JPEG format, which is now widely adopted in order to transfer and store digital images. This is a raster image category file. Full name - JPEG 2000 Code Stream. The J2C file format was created by Joint Photographic Experts Group. A format is a lot of advanced features, including efficient coding. The .j2c file extension is a JPEG 2000 image file. This bitmap is created using JPEG 2000 compression. The compression is close to standard .JPG compression. However, it uses a new coding standard, and it is flexible due to computational complexity. Many applications that support standard .JP2 files can view it. A file with the J2C extension opens in the Windows operating system. To view and process a bitmap image in J2C format, you need to use programs such as Corel PaintShop Pro X9, IvanView, ACD Systems Canvas 16, ImageMagick. Using the programs that have been listed, you can convert images, pictures and drawings of the specified format.
