Color Data Interchange: Technology and Standards

Displaying color images in different media implies the interchange or transmission of color image data. Because transmission utilizes a limited resource (channel bandwidth or capacity), a great deal of effort has been invested in the efficient representation or coding of color images for transmission and storage. The current device-independent or CIE-based standards for color interchange will be reviewed, along with the algorithms for coding image data. It will be noted that current approaches are traceable to a few key ideas that appeared in connection with the emergence of color television around forty years ago.
