    • Image signals are orthogonal-transformed (DCTed) in mutually different dimensions (DMs) to obtain transform coefficients (TC) for each DM, which are then compared mutually to select TC of one DM based on the comparison. Or else, such TC of one DM are selected based on the image signals in a specific DM and the selected TC are quantized and variable-length coded to output coded signals. In another way, prediction error (PE) signals obtained by predictive coding (PC) are DCTed in mutually different DMs to obtain TC for each DM; the TC of one DM are selected based on the PE signals in a specific DM, and then quantized and coded. Or else, the TC obtained for each DM are quantized and then compared mutually. The quantized signals of one DM are selected based on the comparison and then coded. Or else, the TC obtained for each DM are quantized and coded, and coded signals of one DM are selected based on the comparison. The coded signals are transmitted together with mode information (MI) indicating which DM the selected TC are transformed in. The coded signals are decoded, and then inversely quantized (IQed). The IQed signals are inversely DCTed in the DM indicated by the MI.
    • 图像信号以相互不同的尺寸(DM)正交变换(DCT),以获得每个DM的变换系数(TC),然后根据比较相互比较选择一个DM的TC。 或者,基于特定DM中的图像信号选择一个DM的这种TC,并且所选择的TC被量化并且可变长度编码以输出编码信号。 另一方面,通过预测编码(PC)获得的预测误差(PE)信号在相互不同的DM中进行DCT转换,以获得每个DM的TC; 基于特定DM中的PE信号选择一个DM的TC,然后进行量化和编码。 否则,对每个DM获得的TC进行量化,然后相互比较。 基于比较选择一个DM的量化信号,然后进行编码。 否则,对每个DM获得的TC进行量化和编码,并且基于该比较来选择一个DM的编码信号。 编码信号与指示所选择的TC被变换的哪个DM的模式信息(MI)一起发送。编码信号被解码,然后被逆量化(IQed)。 IQ信号在由MI表示的DM中被逆向DCT。
