例句與造句

  1. The elements in the quantization matrix control the compression ratio, with larger values producing greater compression.
  2. To reduce the data rate without significantly reducing quality, the size of the quantization matrix can be used.
  3. where G is the unquantized DCT coefficients; Q is the quantization matrix above; and B is the quantized DCT coefficients.
  4. A typical quantization matrix ( for a quality of 50 % as specified in the original JPEG Standard ), is as follows:
  5. A "'quantization matrix "'is a string of 64-numbers ( 0-255 ) which tells the encoder how relatively important or unimportant each piece of visual information is.
