传统矢量量化编码一般采用绝对误差（如ＭＳＥ）为误差度量准则，并不符合人类视知觉的特性．本文根据人的视觉感知规律，定义了一种可广泛用于图象编码的视觉误差准则（ＭＶＥ），由此导出一种新的矢量量化编码方法．实验表明，采用这种方法得到的解码图象在视觉效果比传统方法有较大改善． Traditional vector quantization coding generally adopts absolute error (such as MSE) as the error criterion and does not accord with human visual perception characteristics. This paper defines a visual error criterion (MVE) which can be widely used in image coding based on human visual perception rules, and derives a new vector quantization coding method. Experiments show that using this method to obtain the decoded image in the visual effects than the traditional method has greatly improved.
