A smoothness metric for colour transforms

Green, Phil (2008) A smoothness metric for colour transforms. In: Proceedings of SPIE 6807 Color Imaging XIII: Processing, Hardcopy, and Applications. Society of Photo-Optical Instrumentation Engineers and Society for Imaging Science and Technology, USA, pp. 1-5. ISBN 9780819469793

Type of Research: Book Section
Creators: Green, Phil
Description:

Metrics are proposed which allow the evaluation of the intrinsic smoothness of an output colour transform. One metric is based on taking the second derivative of the transform. The second method computes a series of smooth gradients and evaluates the differences between these gradients and the actual output values. A psychophysical experiment was performed to evaluate the proposed metrics, and both were found to be highly correlated with the observers' visual scale values.
