Quantization-for-DCT
- 量化离散余弦变换系数的程序实现及其效果的检测。过程中使用了8x8的分块方法。首先计算每块的离散余弦变换（DCT)；然后量化了DCT的系数； 最后进行了反离散余弦变换(iDCT). 程序中还可以设定缩放系数。-Quantify the discrete cosine transform coefficients procedure and its effect detection. The process used in the 8x8 sub-block method. First calcul
dct
- 在编码端，影像首先被分割成8 8块。 DCT的操作，然后 适用于每个图像块。据国际视频标准（JPEG，H.261...）， 变换系数四舍五入到最接近的整数，并剪辑成12位（ 2048至 2047）。这些系数，然后根据锯齿扫描顺序安排到1-D数据阵列。 然后，选择一些系数和量化。在解码器端，量化系数 反DCT（IDCT）重建。 IDCT的输出调整和裁剪，以0 255。 （我们只有Y信号处理。），DCT，量化和锯齿扫描规格 为了下页。 下面
