An adaptive quantization algorithm in distributed video coding

Liang Cai, Dengyin Zhang
Quantizaion is the first step in converting the analog signal into digital signal. In the distributed video coding, a 4x4 quantization matrix is used to quantize each coefficient. However, such a scheme is a fixed quantization matrix and can not be adaptively adjusted according to the characteristics...
