But Ignjatovic and Bocko have laid out the pixels to lie at the peaks of cosine waves resulting in a non-uniformly distributed array, instead of an evenly spaced one. By using this trick, the amount of computation required to compress the image is slashed by nearly five-fold. Since each pixel is positioned exactly where each cosine wave has a peak where the cosine value is "one," multiplying by one is unnecessary. With no multiplication and only a little addition, the processor uses less power.
