Description: 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 the procedure of encoding of an image in the international video standards (JPEG, H.261, ...).
