Abstract
A new grey-level mapping law for direct histogram specification is proposed. Using this law, the accuracy of mapping the original histogram to the specified histogram can be improved. A comparison between this new method and the currently used one with both artificial and real histograms, and a discussion of the error limits of both mapping laws, are also presented.Keywords
