Paper Abstract

An image processing algorithm is presented that adaptively converts color images to grayscale. The intent of the conversion is to preserve color information that is traditionally lost by the conversion process. The conversion produces high-contrast grayscale representations with enhanced color discriminability. A web-based psychometric study confirms that the algorithm is mostly preferred over traditional algorithms. The algorithm employs a multi-stepped approach that includes color clustering, 3-dimensional partitioning, and simulated annealing.
