JPE is the graphic format of the raster image category. It was developed by the standards committee of the Joint Photographic Experts Group. It is a 24-bit compressed graphics format. Typically, it is used for web resources. In most cases, it is used for photographs or images in which there are many colors. Also well suited for many digital cameras to store digital photos. Images that have this extension use lossy compression. And because the quality of individual photos is getting worse. The greater the compression, the less quality the image becomes. The purpose of JPE files is to compress photorealistic images with small color losses. Provides the ability to achieve high compression ratios. We emphasize that usually the maximum compression of graphic information leads to some loss of information. That is, the compression algorithm changes the original data so that the image that is obtained after restoration will be different from the original image, that is, compressed. This compression method is used to work with full-color images that have high photographic quality. During compression, the Discrete-Cosine Transform (DCT), Huffman’s Code quantization and coding are used.
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.
