Abstract: The standard two dimensional block discrete cosine transform suffers greatly from the blocking artifacts when used in compression. A modified block assignment is used to reduce the block discontinuity associated with the standard DCT. The new block assignment spans a strip of several rows or columns. Several sizes of these blocks have been implemented, the smallest is a single line which reduces the two dimensional DCT into one dimension. Both the two and one dimensional strip discrete cosine transforms were used in this paper to achieve compression with considerable reduction in blocking artifacts. © 2005 IEEE.
