然后對(duì)變換系數(shù)應(yīng)用量化矩陣進(jìn)行量化。
Step 3, a preset quantization table matrix is utilized to carry out quantization to frequency coefficient data obtained from forward discrete cosine transform;
步驟3，利用預(yù)設(shè)的量化表矩陣將正向離散余弦轉(zhuǎn)換后得到的頻率系數(shù)數(shù)據(jù)進(jìn)行量化處理；

This control scheme proposes a visual quantization matrix to weight the discrete cosine transform (DCT) coefficients in order to reduce the coding distortion on the visual perceptibility.
該控制策略采用一個(gè)視覺量化矩陣對(duì)DCT系數(shù)進(jìn)行加權(quán)處理，以減少DCT系數(shù)在視覺特性上的編碼失真。
