Cosine Transform∗ Gilbert Strang† Abstract. Each discrete cosine transform (DCT) uses N real basis vectors whose components are π cosines. In the DCT-4‚ for example‚ the jth component of vk is cos(j + 1 )(k + 1 ) N . These 2 2 basis vectors are orthogonal and the transform is extremely useful in image processing. If the vector x gives the intensities along a row of pixels‚ its cosine series ck vk has the coefficients ck = (x‚ vk )/N . They are quickly computed from a Fast Fourier Transform. But a

Climate How cold do you think Russia can get? The Russian winter certainly guarantees plenty of snow and frost… but not everywhere. And it doesn’t last forever. Russia’s climate varies dramatically‚ from the deep Arctic chill of the far north to the searing desert heat of some inland areas further south. Yet‚ throughout much of the country there are only two distinct seasons – winter and summer. Spring and autumn are only brief spells of change in between. [pic]Russian winter (photo by Irina
