This paper presents some results obtained by applying standard image enhancement techniques to improve the readability of ancient manuscripts. We implement adaptive histogram equalisation techniques for the removal of the stain on a particular Greek parchment. We also use the residual from a linear prediction technique to highlight edges in the text. Although the results can reduce the time it takes to decipher a document, the results in their present form do not highlight characters that the reader could not have seen given enough time. There is wide scope for future work in this area and it promises to be most beneficial to the study of ancient text.
