Color images are a fundamental part of daily life in academics, business, manufacturing and leisure. Unfortunately, the actual definition, description and meaning of color remains only vaguely understood by most engineers. For example, most technical people know that color is often represented by a triplet of red, green and blue values, (RGB), but may not be clear about how those values have been obtained, transformed or their relationship to the perception of the displayed color.

This seminar will acquaint the participant with the fundamentals of colorimetry, the science of measuring color, and its application in imaging. We will describe the color characteristics of common imaging input and output devices. The advantages and limitations of the devices and the various forms of color information will be discussed. An important topic is the practical communication of color information and its implementation in a multimedia environment, where various types of input devices need to interface with various types of output devices. The tutorial will indicate current problems, possible research areas and where advanced signal processing techniques can be used effectively.

This talk is part of the Signal Processing and Communications Lab Seminars series.
