Coding jpeg

Although a JPEG file can be encoded in various ways, most commonly it is done with JFIF encoding. The encoding process consists of several steps: 1. The representation of the colors in the image is converted from RGB to Y′CBCR, consisting of one luma component (Y'), representing brightness, and two chroma components, (CB and CR), representing color. This step is sometimes skipped. WebNew work has been started in the JPEG committee to enable the use of JPEG XR image coding within the JPX file storage format — enabling use of the JPIP protocol, which allows interactive browsing of networked images. Additionally, a Motion JPEG XR specification was approved as an ISO standard for motion (video) compression in March 2010.
