摘要： When a two-dimensional DCT is divided into first and second one-dimensional DCTs, a plurality of intermediate results obtained by the first one-dimensional DCT can be read out at a time. Intermediate results .phi.(x, v) are arranged in a new matrix M1 along columns, not rearranged in the same matrix in place of pixel values f(x, y), so that the intermediate results .phi.(x, v) can be read out along rows in the second one-dimensional DCT. That is, the intermediate results can be read out consecutively, or all together if the width of processable bits in hardware or software which performs the DCT is large enough. Further, when u=v, necessary data for process is located in the same row both in the matrices M1 and M2, which enables consecutive readout of the data.
摘要翻译：当将二维DCT分割为第一和第二一维DCT时，可以一次读出通过第一一维DCT获得的多个中间结果。中间结果phi（x，v）沿着列排列在新的矩阵M1中，而不是在同一矩阵中重新排列在代替像素值f（x，y））上，从而可以读取中间结果phi（x，v）在第二个一维DCT中沿着行排列。也就是说，如果执行DCT的硬件或软件中的可处理位的宽度足够大，则中间结果可以连续读出，或者一起读出。此外，当u = v时，用于处理的必要数据位于矩阵M1和M2中的同一行中，这使得能够连续读出数据。
