abstract = "In this paper, histogram uniformization of digital images by means
of the finite field cosine transform (FFCT) is examined. The
approach consists in dividing the image into blocks and applying
the FFCT, in a recursive manner, to each block. Simulations of the
procedure show that the histogram of the transformed image
exhibits a uniform shape and its pixels have low correlation with
their neighbors. This result is achieved due to the modular
arithmetic used in the application of the FFCT to the image
blocks. The suitability of the proposed technique in the context
of image encryption is discussed.",
