quantization matrix造句
例句與造句
- The elements in the quantization matrix control the compression ratio, with larger values producing greater compression.
- To reduce the data rate without significantly reducing quality, the size of the quantization matrix can be used.
- where G is the unquantized DCT coefficients; Q is the quantization matrix above; and B is the quantized DCT coefficients.
- A typical quantization matrix ( for a quality of 50 % as specified in the original JPEG Standard ), is as follows:
- 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.
- It's difficult to find quantization matrix in a sentence. 用quantization matrix造句挺難的
- The resulting block ( the same size as the original block ) is then pre-multiplied by the quantisation scale code and divided element-wise by the quantization matrix, and rounding each resultant element.
- Quantization is performed by taking each of the 64 " frequency " values of the DCT block, dividing them by the frame-level quantizer, then dividing them by their corresponding values in the quantization matrix.
- The quantization matrix is designed to provide more resolution to more perceivable frequency components over less perceivable components ( usually lower frequencies over high frequencies ) in addition to transforming as many components to 0, which can be encoded with greatest efficiency.
- To further reduce the data rate without significantly reducing quality, the size of the quantization matrix can be used, the maximum data rate can be exceeded, and the bit rate of the MP2 audio can be reduced ( or even the use of MP3 audio instead of MP2 audio ).
