D wavelet transform compression coding for image seqUences has been reported recently.
最近有文献报道图像序列的三维子波变换压缩编码。
The image damage by transform coefficients quantization in ID-DCT transform compression coding is analysed on frequency domain and space domain. Some useful results are obtained.
本文对一维DCT变换压缩编码中变换域系数二次量化引起的图象损伤进行了频域和空间域分析，得出了一些有用的结论。
The quantization step is the actual information-losing step where compression occurs; the output values of transform are rounded, mostly to zero, leaving only a few integer coefficients.
量化步骤会进行实际的压缩动作，部分信息会丢失。转换步骤的输出值经过取整，大部分是零，只留下几个整数系数。
