- Discrete Cosine Transform (DCT) and quantization are two critical parts in image encoding. By discussing how coefficients retaining and quantization step selection influence the quality of the reconstructed image, this homework helps to understand th

- 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
