摘要

An inverse discrete cosine transform method is characterized in : first, calculating out the sum of multiple input coefficients for deciding whether the sum is even or odd, and if the sum is odd, in order to make it even, proceeding operation to at least one input coefficient, and then proceeding inverse discrete cosine transform.
