JPEG 2000 is an image coding system and state-of-the-art image compression standard. It uses wavelet technology to code lossless content in any quality at once. Moreover, without any substantial penalty in coding efficiency, JPEG 2000 has the capability to access and decode the same content efficaciously into a variety of other resolutions and qualities. The code streams in JPEG 2000 are significantly scalable having regions of interest that provide the facility for spatial random access.
A JPEG is a type of image format that is saved using the method of lossy compression. The output image, as result of compression, is a trade-off between storage size and image quality. Users can adjust the compression level to achieve the desired quality level while at the same time reduce the storage size. Image quality is negligibly affected if 10:1 compression is applied to the image. The higher the compression value, the higher the degradation in image quality. JPEG image file format was standardized by the Joint Photographic Experts Group and, hence, the name JPEG. The format has been the choice of storing and transmitting photographic images on the web. Almost all Operating systems now have viewers that support visualization of JPEG images, which are often stored with JPG extension as well. Even the web browsers support visualization of JPEG images.
