  In this paper, we propose a new algorithm to make a novel spatial image
transformation. The proposed approach aims to reduce the bit depth used for
image storage. The basic technique for the proposed transformation is based of
the modulus operator. The goal is to transform the whole image into multiples
of predefined integer. The division of the whole image by that integer will
guarantee that the new image surely less in size from the original image. The
k-Modulus Method could not be used as a stand alone transform for image
compression because of its high compression ratio. It could be used as a scheme
embedded in other image processing fields especially compression. According to
its high PSNR value, it could be amalgamated with other methods to facilitate
the redundancy criterion.
