摘要
提出了一种新的色系坐标系r'g'b',在这种坐标系下,无须对色度信息进行经验公式修正;并推导说明了在无法估计非肤色条件样本的概率分布情况下,用肤色分布先验概率来表征肤色点后验概率的原理。
A new set of color coordinates r'g'b' is presented,under this set of coordinates,experiential adjustment to chroma values will be no longer needed;and a principle has been deduced and explained to reflect the afterwards probability with beforehand probability under the condition that the probability distribution of a non -skin color conditional sample is unestimatable.
